My 3 Questions :
What is the ratio for blue to pink to total ?
What could the fraction 1/2 represent in this picture ?

Part 2:
3. A normal deck of playing cards has 52 cards in four suits (clubs, diamonds, hearts, spades) of 13 cards each. Two of the suits are black and two of the suits are red. The ratio of red cards to the whole deck is ...
mistake : 2:4
right answer : 1:2
5. Erci is able to stop 85 % of the shots on goal. If he faces 27 shots on goal, how many goals would likely be scored on him ?
mistake : 15
right answer : 4
In a group of 84 students surveyed, the ratio of student preference is seven oatmeal eaters to four granola eaters to three toasted 0 eaters.
14. What percent (to one decimalplace) of the group prefers toasted 0's ?
mistake : 18.7 %
right answer : 21.1 %
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 ?
mistake : 6/8 = 1/3
right answer : 6/8 = 1/3 red balls : whole bag of balls
In the future I should read the questions clearly so that I'll see that I need the answers to be in lowest terms.
Next time I should pay attention to my ratio table so that I won't make any mistakes on my answers.
Next time when I'm trying to find a percent i should double check my ratio table to see if its correct.
2 Questions :
Alex is able to stop 65 % of the shots on goal. If he faces 36 shots on goal, how many goals would likely be scored on him ?
In a group of 75 students surveyed, the ratio of student preference is five oatmeal eaters to eight granola eaters to two toasted 0 eaters.
What percent (to one decimal place) of the group prefers toasted 0's ?

1) 65/100 = ?/36
0.65 x 36 = 23.4
65/100 = 23/36
36 - 23 = 13
13 goals would likely be scored on him.

2) 100 ÷ 75 = 1.3
1.3 x 10 = 13.3
13.3 % of the group prefers toated 0's.
