Jarret873, BOB 2

What I Learned And What I Need To Work On

I really need to work on studying more and paying more attention in class.

I got to learn how to do a ratio table

1. Whatever You Do To One Side You Must Do To The Other
2. Study!
3. Pay more attention
   

I have to learn how to get the answers questions faster. I have to remember to check my work over, as much as possible to make sure things are as right as it seems, because doing things the faster way doesn't always turn successful "specially" in math.

Alexander's BOB Ratio

Part To Part Ratios:
Blue to Green- 9:2
Orange to Green- 7:2
Blue Vowels To Blue Constants - 5:4

Part to Total Ratios:
Blue to Total -9:18
Orange to Total-7:18

Three Part Ratio
Blue to Orange to Green - 9:7:2

Ratio Notation, Fraction, Decimal, and Percent
Punctuation to Constants
P/C- 1/8, 0.125:1, 12.5%:100%

Equivalent Ratios
Equivalent Ratios are ratios that equal the same. E.g. 10:2 and 5:1 are equivalent.
To make equivalent ratios you can divide or multiply, but always do what you do to one side to the other.

Questions
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.

Allen's BOB Ratio

Part to par t ratios:
blue to orange - 9 : 6
vowels to consinents - 7 : 8
A to E -3 : 2

Part to total ratios:
blue to total - 9 : 16
consinents to total - 8 : 15

Three part ratio:
blue to green to orange - 9 : 1 : 6



Ratio notation, fraction, decimal, and percent

vowels to consinents - 7 : 8
v/c - 7/8 = 0.875 = 87.5%



Equivelent ratios.
You can make equivalent fractions by multiplying or dividing the ratio. But you always have to remember to always do what you did to one side you always have to do to the other





Questions.
1) Show A to E or 3 : 2 in ration notation, fraction, decimal, and percent.
2) Explain what is a equivelent ratios?
3) Make an equivalent ratio of 7 : 8?

Please remember to answer the questions on your comments.

What i need to work on.

red/total = 26/52

red/total = 2 / 4 = (1/2)

My mistake is by not putting the ratio in lowest term.

On the future test will put the ratios in lowest term even if it doesn's say to simply.

total = 30 students

3+15+6 = 24

30-24 = 6 votes for Karen

My mistake is by not following the order of word ratio.

On future test ill reread the test to make sure the i follow the word ratio order.

My mistake was not understanding the question.

On future tes i will try my best to understand a question.

1. Show 3:1 as a fraction, decimal, and percent?

2. Give an equivalent ratio to 4:3?

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

Thank you for viewing my post everyone! Don't forget to comment. Remember to study. Good look on your tests! :)

BOB 2

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.

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?

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?

Raquel's Bob & Ratio

PART TO PART RATIO:
Green:Blue 6:1
Blue:Red 1:10
Yellow:Blue 6:1

PART TO WHOLE RATIO:
Red:Total 10:23
Blue:Total1:23

3 PART RATIO:
Green:Blue:Yellow 6:1:6
Total:Letters:Green 23:7:6

Here is the ratio that I picked to show a ratio notation, fraction, decimal, percent. Blue:Red. Here is how I did it:
Ratio Notation: 1:10
Fraction:1/10
Decimal: 0.10
Percent:10%
I got the fraction by adding up the numbers of blue m&m's and red m&m's. I got the decimal by dividing the fraction and I got the percent by multiplying the decimal by 100.

Making An Equivalent Ratios
blue to red, 1:10 2:20 3:30 4:40 5:50. These are all equivalent fractions. When your trying to make an equivalent fraction you have to know that if you do something to one side you do it to the other. So, 1:10 is equivalent to 2:20 because you multiplied 1 by 2 and so what you do on one side you do it on the other by doing that 10 times 2 equals 20. So the ratio is 2:20.

3 QUESTIONS
1: If you make a ratio of blue:total. What would be the fraction decimal and the percentage be and How did you do it?
2: What would the equivalent ratio look like if it was 6:1?
3: What if there was 3 more blue then red? What would the fraction decimal and percentage look like?

THANKS FOR READING
(P.s The ratios might be wrong cause I may have miss counted it. )
Anyways. Byeeeeeeeeeee. :D

---------------------------------------------------------------
PART 2

What were the mistakes you made on your test. Show examples of answers that were wrong. What was your mistake. How will you remember what to do in future tests?

- Some of the mistakes I did on my test was that I didn't read the question carefully. I forgot to simplify my work cause I forgot to. I also didn't show my work so that's why I did bad on my test. I also need to write on my paper on showing how I got the answer. The next time I do a test, I will study more harder so that I know what to do. I will also try my hardest to read the question carefully and show how I did it using ratio tables etc.

RE-WRITE 2 QUESTIONS THAT GAVE YOU DIFFICULTY WITH DIFFERENT NUMBERS.

- Four students are running for student council president. Of 60 students polled, 30 chose Mike, 6 chose Patricia, 12 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.

Jerick873 BOB Ratio

This is my Bob blog for extra marks .

First I must make 3 part-to-part ratios :

a) green to yellow - 7:5

b) blue to red - 2:10, 1:5

c) green to red- 7:10

Next I must make 2 part-total ratios:

a) green to total - 7:24

b) red to total - 10:24

Now I must make 2 part-to-part-to-part ratios:

a) yellow to blue to green - 5:2:7

b) red to green to total- 10:7:24

Here is my ratio expressed in ratio notation, fraction, decimal, percent, and word form

2:10(1:5) , 1/5, 0.2 , 20%, blue to red. To do this , when the ratio is in a fraction you divide the two numbers and you get the decimal form and to get to the percentage form you multiply the decimal by 100 because percents are out of 100

Here is where I show how to create equivalent ratio

blue to red 2:10, 4:20, 6:30, 8:40, 10:50 . To make equivalent ratios , what you got to keep in mind is , Whatever you do to one side you have to do to the other , so 2:10 is equivalent to 1:5 ... so you divide the 2 by 2 and since you did that to one side you have to do it to the other so 10 divided by 2 is 5 so 1:5.

Here are my 3 questions

1. What is the ratio of yellow to red?

2. What is an equivalent ratio to 2:24 (blue to total)

3. Show 2:4 as a fraction , decimal and percent.

BONUS QUESTION

1. Do you like M&Ms?

THANKYOU FOR READING THIS POST

p.s. you dont have to answer the bonus question it was just for fun :D and the other blue is on the left side squished in with between 2 reds and one green

Part 2 Bob 2

Well part is about my test , to be honest im kind of proud of my mark but i know there is still room for improvement .

Well my mistakes on my test mostly had to do with simplifying. Example

18:27 , i put 6:9 and it said to express in lowest terms but i didn't put it in lowest terms , but the answer would of been 2:3.

and there was another one about the cards in the deck. red cards to whole deck and i answered 2:4 , i forgot to simplify and 1:2 was there. But in my defense it did not say express lowest terms but I guess it was my fault cause we always have to simplify.

fraction: 3/2

decimal: 1.5

percent: 150%


5. Equivalent Ratios

3:2

To make a equivalent ratio you can multiply or divide the number. For example, 6:4 /2 = 3:2
6:4 x 2 = 12:8.


6. 3 questions

what is the ratio of red to green ?

Is the ratio equivalent ? if so, why ? if not why ?

What is the part to total ratio of orange ?

Bob part 2

What mistakes I did and how can I improve it.

I made alot of mistakes, I didn't simplify the answer. For number 17 i put 115/92 = 10/6. I put 6 instead of 8 and i didn't show my work. I can improve my mistakes by simplifying the answer, read the question carefully, think about the question before I answer, and re- read my test before I hand it in.

Rewrite 2 questions that gave me difficulty.

Four students are running for student council president. Of 30 students polled, 14 chose Mikey, 5 chose Patty, 7 chose Bria,and the rest chose Kara. What is the ratio for votes for girls to boys in the student council election? Express the ratio in the lowest terms.

19:11 11:19 16:3 14:7

You have 6 red balls, 8 yellow balls, and 3 blue balls. In lowest terms , what is the ratio of red balls to total balls ?

17:6 8:3 6:17 9:3
