Question

Martha is making 5 batches of cookies. Each batch uses 3/4 cup butter. How much butter does she need for all of her cookies?

A.
3 3/4 cups butter
B.
3 1/2 cups butter
C.
3 1/4 cups butter
D.

Answer 1

3 1/2 cups butter

Explanation:

Multiply the batches (5) by the amount of butter (3/4 cup)

5/1 * 3/4 = 5*3 = 15; 1*4 =4 15/4

Divide 15 by 4 to turn from improper fraction to mixed number:

15/4 = 3 and 2/4; reduce to 3 1/2
