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