3/4
1 1/2
2 1/4
2 5/8
How many cups of blueberries will Marco need if he has 2 cups of flour to use?
A.
1
1/3cup
B.
2/3 cup
C.
1 1/2 cups
D.
6 cups
To find the number of cups of blueberries needed for 2 cups of flour, we look at the ratio in the table. From the table, we can see that for 3/4 cups of flour, we need 1/2 cup of blueberries. Therefore, for 2 cups of flour, we can set up a proportion:
(3/4 cup flour) / (1/2 cup blueberries) = (2 cups flour) / (x cups blueberries)
Cross multiplying, we get:
(3/4 cup flour) * (x cups blueberries) = (2 cups flour) * (1/2 cup blueberries)
Multiplying, we have:
(3x/4) = (2/2)
Simplifying, we get:
3x = 4
Dividing both sides by 3, we find:
x = 4/3 = 1 1/3
Therefore, Marco will need 1 1/3 cups of blueberries if he has 2 cups of flour to use.
The correct answer choice is:
A. 1 1/3 cups
