Question

Trail Mix is sold in 1 pound bags. Mary will buy some trail mix and re-package it so that each of the 15 members of her hiking club gets one 2/5 pound bag. How many 1 pound bags of trail mix should Mary buy to have enough trail mix without leftovers?

Answer 1

Okay. so we need 15 2/5 pound bags. We'll calculate how many pounds that actually comes to. Our problem is 15x2/5. Using cross simplification, our problem becomes 3x2. 3x2=6. We need 6 pounds. That means that we must have 6 1-pound bags to fit with no leftovers.
