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?
