Four 4's



These two equations are the same even though one is using a fraction while the other is using a division sign , but they do both mean the same thing.

You can write divide like 4/4 or 4÷4 they equal the same thing just written in a different way.

how much do the coins add up to ?
All the coins in the jar add up to $100

Would the jar look the same if the money was Canadian?
It would have less of each coin because Canada has Loonies and Toonies compared to Americans that have bills as dollars. So it would look a lot less if it was all Canadian.

Coin Math part 2

If you started dropping coins into the jar on January 1 , 2010, what day would you finish filling up the jar?

If the jar was filled with all american coins, it would have 1280 coins in it. This filled up 3 quarters of the jar. If you find how much coins can fit in the whole jar it will make this problem easier. So what you do is find how much 1280 divided by 3 multiplied by 4 is.
This gives you about 1707.

So if there is 1707 coins in there jar it would take me approximately 4.79 years to fill the whole jar by putting one coin in it each day. So it would take be around 4 years, so what I'm thinking that it is 79 percent of the year, and that would be around 284 days, I estimate 4 years and 284 days,
That would be October 11, 2014.

How much of the jar is filled with Canadian coins ?

The jar has 370 coins in it. We have found out that 3/4 of the jar is 1280 , so if you divide that by 4 you get 320 , so now we know its more than 1/4 of the jar. So I'm guessing its around 27-30 percent of the whole jar.

Mikayla's ration scribepost





There are different ways to write a ratio.
For example, 4:12
1. As a fraction.
4/12
2. As a decimal.
To turn a fraction into a decimal, divide the numerator by it's denominator.
4/12 = 0.33
3. As a percent.
To turn a decimal into a percent, move the decimal point two places to the right.
0.33 = 33%
PS: you can also simplify the ratio.
Ex: 4:12 = 1:3
( I divided both number by 4. )

Mikayla's Coin math

Questions :
What is the value of each type of coin in the jar?
Canadian coins
penny= 1 cent
nickel= 5 cents
dime= 10 cents
quarter= 25 cents
loonie= 1 dollar
twoonie= 2 dollars

How many more coins would it take to fill up the jar?
The jar is about three-quarters full. So if you add a quarter more of the number of coins that are in the jar, then the jar would probably be full.

If the jar was filled with Canadian money, would you need more coins?
No, because unlike US dollars, Canadian money has more coins. So for example, instead of having four US quarters, we can just put one Canadian loonie.

a) Cool Flavours obviously produced this graph to make you think that they have a big difference from Dairy Taste. Actually there is only $0.2 million of a difference between Cool Flavours and Dairy Taste.

b)This graph is misleading because it makes you think that there is a big difference in the sales of the two ice cream stores when the truth is, there is only $0.2 million of a difference.

The four 4's


Both equations may seem different but they are actually the same. The reason they look different is because one is written horizontally and the other is written in fraction form. The fraction bar means the same as the division symbol, that's why these two equations mean the same thing.

Vicky's Post Question 16

Heather used a copier to make the following 50% reduction.
(I CANNOT PROVIDE A PICTURE, MYTEXTBOOK DOES NOT WORK)
a) Write the ratio of the length A'B' compared to the length of AB.
The ratio of the length of A'B' compared to the length of AB is 1:2
b)Write the ratio of the length of A'C' compared to the length of AC
The ratio is also 1:2
c)Use your knowledge of ratio and percent to explain the meaning of a 50% reduction.
50% reduction (ratio) is like 2:4 that is reduced by a half / 1:2. In percent it is like 100% turned into 50%

Hello!

Hello everybody!

This is Kim, your student mentor! Hope you all are having a great week!

I'm just wondering, what can I do to help you in this class? Do you have any ideas?

The site you guys have here looks pretty cool. I think math would have been easier for me in grade 8 if I had a cool website like this to keep notes organized. Do you guys like having class like this too?

Do you have any questions for me? I was thinking that I better make an effort to make myself known as me, instead of the crazy person who posts pirate videos.

Speaking of which, here is another one. Tell me what you think.

BOB
The Three things I know about graphing are:
1.) There is always an interval on a bar graph(a.k.a bar chart), line graph, double bar graph, and double line graph.
2.)There are 3 ways you can mislead a graph or distort : Distorting the Scale , Distorting the Size of the Bars and Distorting the Visuals.
3.)Line graphs are for showing something over time. Bar graphs are for comparing data by categories or groups(i think). Circle graphs are best for comparing data by using percents. Pictographs are best for comparing data using pictures as a representative.
What I know that would improve my test:
I could've improved if i put more information, exspecially better sentences(which I didn't do). Plus maybe i Should've used that paper that was handed out. && I should've made everything better, like my drawings, my writing etc.

BOB and ratio


Ratios:
Part to pat
Shades of green to shades of pink ( 3:2 )
Shades of blue to shades of purple ( 3:1 )
Orange to green ( 1:3 )

Part to total
Blue to total ( 3:12 )
Pink to total (2:12)

Three- part
Green to purple to pink (3:1:2)
Total to blue to purple (12:3:1)


Ratio notation, Fraction, Decimal, and Percent

Shades of green to shades of pink ( G:P ) 3/2 , 1.5 , 150 %

Equivalent Ratios

Equivalent ratios are two ratios that have the same value when simplified. For exaple, 3:12 is the ratio of green colored crayons to the total number of crayons. 1:4 is equivalent to 3:12 because 3 and 12 and both divisible by 3. Divide both 3 and 12 by 3, and you get 1:4.

Questions

1) Basing on the picture above, make a ratio of the number of vowels to the number of consonants. Express it in lowest terms.

2) How do you know if you can or cannot simplify a ratio ?

3) In lowest terms, make a ratio of the number of blue crayons to the total number of crayons.

BOB2

The mistakes I did on the test were mostly on the multiple choice questions. I just didn't put the ratio in the right order. The answer is supposed to be 3:7, but instead I chose 7:3. Another mistake I did was that I got the wrong answer for finding the percent.


4. Four students are running for student council president. Of 30 students polled, 15 chose Mikw, 3 chose Patricia, 6 chose Brian, and the rest chose Karen. What is the ratio of votes for girls to votes for boys in the student council election? express the ratio in lowest terms.

a. 3:7 b. 7:3 c. 15;6 d. 21:9

Votes for girls: votes for boys

9:21

9/21 divide by 3/3

Equivalent Ratios
Equivalent Ratios are ratios that equal the same. E.g. 10:2 and 5:1 are equivalent.

1) What would be a part to part to whole ratio?
2)Show Orange to green or 7:2 ratio notation, fraction, decimal and percent
3)Make an equivalent ratio of blue to green, or 9:2



PART 2

1 mistake I made was in reading the question and figuring out the ratio order. Like in the question where it asked what was the vote of girls to guys, I put it in the order of guys to girls. For future test I will remember to read over my questions.

1 question I got wrong was the picture frame question. I put 11cm instead of 12.6cm.

  • 52 cm x 120.5 = 2.31
  • 348 mm x 565 mm = 1.62 Golden rectangle

I got the answers NOT by multiplying the length and width but by dividing the length by the width.

The mistakes I made on my test were:
Multiple Choice-
4. Four students are running for student council president. Of 30 students polled, 15 chose Mike, 3 chose Patricia, 6 chose Brian, and the rest chose Karen. What is the ratio of votes for girls to votes for boys in the student council election? Express the ratio in lowest terms.
- My answer was d/21:9. The actual answer was a/3:7. My mistake was I misread the question/word ratio. In the future I will read through the question twice.
7. A rapid transit train has 39 passengers on it as it starts its run. At the first stop 12 passengers get off and 18 passengers get on. What is the ratio of the number of passenger who were on the train as it arrived in the first station to the number who were on the train when it left the first station? Express your answer in lowest terms.
- My answer was d/27:39. The acutal answer was b/13:15. My mistake was I didn't read the question well enough. In the future I will read the question more well.
8. A picture frame has a width to length ratio of 5:7. If the width of the photo is 9 cm, the length of the photo of the photo is.
- My answer was a/11cm. The actual answer is b/12.6 cm. My mistake was I thought that you could use addition in ratios. In the future I will not use addition in ratio questions.
Completion
14. What percent (to one decimal) of the group prefers toasted O's?
- My answer was 15.1%. (Sorry, I dont know the actual answer to this question.) Next time I will use a ratio chart to solve the question.
Short answer
15
D. Write each ratio in lowest terms. (18:27)
- My answer was 9:13.5. The actual answer was 2:3. In the future I will try to find more ways to get the correct answer.
16. You have a bag with one white ball, six red balls, eight green balls, and three purple balls. In lowest terms what is the ratio of red balls to the whole bag of balls?
- My answer was 1:2. The actual answer was 1:3. My mistake was I thought that the question meant the red balls compared to the rest of the balls. But now I know that it means all of the balls together compared to that group.
17. Use the data in the table below to determine which sports teams have equivalent scored by to scored against ratios.
- My answer was Baseball Team A and Hockey Team A. The actual answer was Baseball Team A to Basketball Team A. My mistake was I thought the answer was about addition. But it was actually about division. In the future I will not use addition.

Bob Ratio


Part to Part Ratio.

Blue :Green(1:6), Yellow:Green(4:6),Yellow:Blue(4:1

Part to Total Ratio.

Blue:Total(1:18),Yellow:Total(4:18),Green:Total(6:18)

Three Part Ratio

Blue:Yellow:Green(1:4:6),Green:Blue:Total(6:1:18

Show one ratio as a ratio notation.

I piked 4:6 (Yellow:Green)

Fraction 4/6, Percent 67%, Decimal 66.6.

You can always get equivalent ratio by dividing and multiplying ratio.

Three questions.

1.Give me three ways to show 1:18?

2.1:6 what does this ratio represent?

3.4:1 what does this ratio represent?

Caitlin.T's BOB Ratio



1.) THREE, PART-TO-PART RATIOS:
a.) green to yellow - (3:2)
b.) pink to grey - (2:1)
c.) peach to blue - (1:4)
2.) TWO, PART TO TOTAL RATIOS:
a.) orange to total - (2:22)
b.) white to total - (1:22
3.) TWO, THREE PART RATIOS :
a.) pink to green to blue - (2:3:4)
b.) peach to yellow to orange - (1:2:2)
4.) Here is my ratio in ratio notation, fraction, decimal, percent, and a word form:
The ratio i chose was green to yellow.
Ratio Notation: 3:2
Fraction: 3/2
Decimal: 1.5
Percent: 150%

To get the the fraction you should know the ratio notation, then to get the decimal you have to divide the numerator and the denominater of the fraction. Then to get the percent you multiply the decimal by 100, then you get your answer.

Making An Equivalent Ratio

To make equivalent ratios, you have to know that if you do something to one side that you do it to the other side as well.

3 Questions

1.)What would some of the ratios be in the lowest terms?
2.) Give me one equivalent ratio for 2/1?
3.)Show how the ratio peach to blue could be shown as a fraction,decimal, and a percent.


BOB 2

I made lots of mistakes in my test, but I'm going to tell you two of them that didn't really make any sense to me when I got to them.

The first one was -

8.) A picture frame has a width to length ratio of 5:7. If the width of the photo is 9 cm, the length of the ph0to is

I got this answer wrong b/c i just guessed, But next time for me to remember I will, get the length to width ratio then get the other length (9) and then make it into a equivalent fraction, then multiply 5 and 1,8 to get to 9 then do it to the other side too. So it would look like 5/9=7/?
then like I said earlier multiply the fraction by 1.8, then y answer for 7/? would be 12.6.(I got 1.8 from dividing 5 and 9.

Another One-

18.) In a student election Carol gets 60% of the votes. If there were 485 votes cast, how many votes did carol get?


I didn't get to answer it b/c I was still trying to figure out the answer. But a way for me to remember to answer it correctly is that, I would use a ratio table starting with VOTES and on the other side it would be 60%.

The two questions-

10. What percent of all the phones were Motorola?
a. 14.4% b. 25% c. 50% d. 77%


18. In a student election Carol gets 60% of the votes. if there were 485 votes cast, how many votes did carol get?

GREETINGS!! (:


















PART TO PART RATIO'S

1. - related to blue to related to green
- 3: 3
- 3 to 3
- rtb/ rtg = 3/3
- 1.0: 1
- 100 % :100
- Im not sure if theres an equivalent ratio for this one..

2. - 1 word to 2 or more words
- 1: 2
- 1 to 2
- word/ words = 1/2
- 0.5: 1
- 50% :100
- 1/2 = 12/24 ( I multiply the numerator and the denominator by twelve )

3. - vowels to consonants
- 43: 77
- 43 to 77
- v/ c = 43/ 77
- 0.55: 1
- 55.8 % :100
- 43/ 77 = 86/ 154 ( I multiply the numerator and the denominator by 2 )

PART TO WHOLE RATIO

1. - blue's to total
- 3: 12
- 3 to 12
- b's/ t = 3/12
- 0.25= 1
- 25% =100
- 3/12 = 1/4 ( I divided the numerator and the denominator by 3 )

2. - a to all vowels
- 6: 43
- 6 to 43
- a/ all vowels = 6/43
- 0.13= 1
- 13. 9 % = 100
- 6/43= 18/ 129 ( I multiply the numerator and the denominator by 3 )

THREE PART RATIO

1. - gold , green's to blue's
- 4: 3
- 4 to 3
- gold, green's/ blue's = 4/3
-1.33 (continuous) : 1
- 133.3 % : 100
- 4/3 = 8/6 ( I multiply the numerator and the denominator by 2 )

2. - green's , silver to total
- 4: 12
- 4 to 12
- green's, silver/ total = 4/12
- 0.33 ( continuous ) : 1
- 33.3 % : 100
- 4/12 = 1/3 ( I divide the numerator and the denominator by 4 )

QUESTIONS:

1. Fractions,decimals and percents are like a chain. Tell me why or why not? Explain and show your answer.

2. How do you make a fraction for a three part ratio?

3. If you were ask to make another part to part ratio about this picture besides for the one I have, what would it be? Tell me the ratio notation, fraction, decimal, percent and its equivallent ratio.


PLEASE ANSWER THE FOLLOWING QUESTIONS AT THE COMMENT BOX!! (:
THANKS FOR READING MY POST! GOOD LUCK FOR THE TEST TOMORROW!! HOPE YOU'LL DO GOOD!! (:
AND DONT FORGET TO COMMENT!! (:



Byeee!! (:


BOB2
This is my bob for extra marks. I almost failed my test so that I need to work on some stuff. Like when to use a ratio table, I have no idea when to use a ratio table ( that's embarrassing ). Like the last question.

18) In a student election Carol gets 60% of the votes. If there were 485 votes cast, how many votes did Carol get?
My answer is 194 instead of 291. When I was doing the test, I have no clue what to do until when we went over it in class. I didn't know that we have to use a ratio table to show our work. What I did was I used a calculator. I kinda guess.

The other mistakes I got is kind of like the same thing as the one above because they all use ratio table to find the answers..

Question:
1. How do you know when to use a ratio table?
