Question

A pastry recipe calls for 3 cups of flour to make 8 servings. How many cups of flour are needed to make 6 servings?

2.25 cups

2.5 cups

4.5 cups

16 cups

Answer 1

You need 2.25 cups for 6 serving

Answer 2

2.25 cups

Explanation:

Set up a proportion and solve for x...

3 cups is to 8 servings as 'x' cups is to 6 servings...

becomes...

3/8 = x/6 now solve for x...

[3(6)]/8 = x (multiply both sides by 6 to get rid of the fraction on the right)

18/8 = x

9/4 = x

2 1/4 = x

2.25 = x
