3.What is the decimal for '7:6' (Green:Yellow)
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.
-I learned how to use a ratio table
- I need to improve on showing my answer in lowest terms.
- I also need to read the questions more carefully so i don't forget out any important details.

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.
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 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.
Determine the unit rate in each situation.
a) Brandon runs 150 m in 25 s.b) Kira earns $88 for working 8 h.c) Cat food costs $9 for five cans.
Answer:
A.)150÷25=6 meters per seconds
B.)88÷8=11 per hour
C.)9÷5=1.8 per can
At Ed’s Grocery, one brand of salsa is sold in the following containersizes. Which container of salsa is the best buy? Show your work.
1. $3.44 ÷ 475mL=0.0074
2. $6.29 ÷ 642mL=0.00979
3. $15.49 ÷ 1.7L=9.111L
Container no. 3 is the best buy salsa.
What I learned and Need to work on
- I cant express my answer in lowest terms .
- I also need to work on equivalent ratios.
- I learned how to make equivalent fractions.
I have to start asking more questions in class when I dont understand.
What I learned and what i need to work on:
1>what would be ratio of red and green yellow to blue to total?
blue to yellow is 5;2 green to blue is 2:5 red to blue 5:2
2>what would be the ratios of green to yellow? 7;6 3:5
3>how many part ratio are there? three part of ratio
Tyler counted 20 cars in the School parking lot. Of these 6 were red, 4 were green, and 1 yellow.
a.) Show how to represent the situation?
20 cars, 6 red, 4 green, yellow.
b.) How many cars were not red,green,or yellow?
add the all the car color and and subtract the total and you should get 9.
Example 6+4+1-20=9
c.)What is the ratio of yellow to green to red cars
6:4:1
d.) What is the ratio of red to total cars? Express the ratio as a fraction and a percent?
6/20 6 divided by 20 multiply b 100 gives 35 percent
Question #5:
a) $2 compared to $8.
2:8.
b) The width of the cover of this book, compared to it's length in centimeters.
width: 21cm length: 26cm. 21:26.
c) A class has 14 girls and there's 30 students, ratio, Boys:Girls:Total.
16 boys, 14 girls, 30 students. 16:14:30.
d) My age compared to a 28 year old.
13:28.
Question #6: Write each ratio in Question #5 as an equivalent ratio in lowest terms.
2:8 - 1:4.
21:26 - 21:26.
16:14:30 - 8:7:15.
13:28 - 13:28.
What I learned and what i need to work on
- I learned how to use a ratio table.
- I need to improve on showing my answer in lowest terms.
- I also need to read the questions more carefully so i don't forget out any important details.
What I need to improve on.
1. I need to improve on reading the questions carefully because if don't I cant answer any word problem ratio.
2. I also need to understand the word problem carefully. And I was struggling. So I need to understand the problem carefully.
What I Learned and Need to Work on
I sometimes need to remember stuff, because
every time we learn something new, I sometimes forget.
I learned how to make ratios in lowest terms easier
ways
I will improve by paying more attention and
making sure if I'm doing something right or wrong
Question #16
Heather used a copier to make the following 50% reduction. 
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.
A 50% reduction is where something is reduced by 50%, that means it will be cut in half. Example if 100 would be reduced by 50% it would become 50
Yes I know it's late but I can't get to my text book so I had to use alternative sources.

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.

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
=3/7 = 3:7

-white to total (1:22)
-orange to total (3:22)
Three part ratio
-grey to yellow to white (1:2:1)
-green to blue to brown (2:4:3)
Ratio notation, fraction, decimal, and percent
-yellow to blue (2:4, 2/4, 0.5, 50%)
Equivalent ratios
-yellow to blue (2:4)
-2:4 is equivalent to 4:8, 5:10, 6:12, etc.
You can find equivalent ratios by multiplying or dividing both sides by the same number. It is similar to finding equivalent fractions.
