Question

Andrea baked 3 cakes for her cousin's birthday. Each cake requires 3 1/4 cups of flour. How many cups of flour was left if she had 15 cups in the beginning? *

Answer 1

5 1/4 cups of flour

Explanation:

Each cake requires = 3 1/4 cups of flour

She has = 15 cups of flour

She made 3 cakes

Number of flour used for 3 cakes = 3 1/4 cups of flour × 3

= 13/4 × 3

= 39/4

= 9 3/4 cups of flour

Flour remaining = Total flour - used flour

= 15 - 39/4

= 60-39/4

= 21/4

= 5 1/4 cups of flour
