Marco is making blueberry muffins. The ratio between flour and blueberries for the recipe being used is shown in the table below.

Question

Cups of
Flour Cups of
Blueberries

3/4 1/4

1 1/2 1/2

2 1/4 3/4

2 5/8 7/8

How many cups of blueberries will Marco need if he has 2 cups of flour to use?

A. 2/3 cup

B. 2/3 cup

C. 1 1/2 cups

D. 6 cups

Answer 1

B. 2/3 cup

To find the ratio of cups of blueberries to cups of flour, we can divide the cups of blueberries by the cups of flour:

1/4 / 3/4 = 1/3
1/2 / 1 1/2 = 1/3
3/4 / 2 1/4 = 1/3
7/8 / 2 5/8 = 1/3

So, for every 3 cups of flour, Marco will need 1 cup of blueberries. Since he has 2 cups of flour, he will need (2/3) cups of blueberries.
