Answer is A
If you would like to know how many cups of flour are needed to make 6 servings, you can calculate this using the following steps:
3 cups of flour ... 8 servings
x cups of flour = ? ... 6 servings
3 * 6 = 8 * x
18 = 8 * x /8
x = 18/8
x = 9/4
x = 2 1/4 cups of flour
The correct result would be 2 1/4 cups of flour.
