Question

Chad and his two friends are picking blueberries at a local farm. Chad picked 2 1/2 pounds of blueberries, and one of his friends picked 1 3/8 pounds. If they ended up with a total of 5 1/4 pounds, how many pounds did Chad's other friend pick? Express your answer as a mixed number.

Answer 1

2 1/2 = 5/2
1 3/8 = 11/8
5/2 + 11/8 = 31/8

5 1/4 = 21/4 = 42/8
42/8 - 31/8 = 11/8

11/8 = 1 3/8 pounds
