Marco is making blueberry muffins. The ratio between flour and blueberries for the recipe being used is shown in the table below.
3/4 Cups of
Flour 1/4 Cups of
Blueberries
How many cups of blueberries will Marco need if he has 2 cups of flour to use?
A.
1/3 cup
B.
2/3 cup
C.
1 1/2cups
D.
6 cups
To find the number of cups of blueberries that Marco will need if he has 2 cups of flour, we can set up a proportion.
The ratio of flour to blueberries is 3/4 cups of flour to 1/4 cups of blueberries.
Setting that up as a proportion, we have:
3/4 cups of flour / 1/4 cups of blueberries = 2 cups of flour / x cups of blueberries
Cross-multiplying, we get:
(3/4) (x) = (1/4) (2)
Simplifying, we have:
3x/4 = 2/4
Multiply both sides by 4 to get rid of the denominator:
3x = 2
Divide both sides by 3 to solve for x:
x = 2/3
Therefore, Marco will need 2/3 cup of blueberries if he has 2 cups of flour.
So the correct answer is B. 2/3 cup.
