Answer 1

1. Runner A

2. Baker 2

3. Blend B

4. Ms. Fiorucci

Explanation:

1. 45/5= 9, but 14/2 = 7 so the ratio is 9:7 so obviosly Runner A is faster

2. 2: 3 1:2 2 = 2 x 1, but 2 x 2 is 4 so that means Baker # 2 used more flour.

3. The ratio is 3:2 and 6: 5 . 3 x 2 = 6, which can be proportinal but 2 x 2 is not 5 and it should be 4 in order to be proportional but since 5 is greater than 4, Blend b has more milk per strawberry.

4. 63/2 is 30 1/2. but 100/5 is 20 so Ms. Fiorucci has more students per class
