Question

Danielle is making protein balls. She uses 1 1/2 cups of protein powder, 2 1/4 cups of peanut butter, and 2/3 cup of honey. Which equation represents the total number of cups of ingredients Danielle uses?

Answer 1

The answer is 4 5/12

Answer 2

4 (5/12). four and five-twelfths

Explanation:

1/2 is the same as 2/4, so: 1 1/2 = 1 2/4

1 2/4 + 2 1/4 = 3 3/4

3/4 and 2/3 have a LCM or least common multiple of 12

4 x 3 = 12 and 3 x 4 =12; but whatever you do to the bottom you have to do to the top (3/4) turns into (9/12) and (2/3) turns into (8/12)

9/12 + 8/12 = 17/12 or 1 5/12 as a mixed number

3 + 1 5/12 = 4 5/12
