Lizzy: Sammy has 8 gifts to wrap. Each gift requires 1.5 meters of ribbon. Unfortunately, she has no available ribbon so Tom let her use his 15-meter long ribbon. How many meters of ribbon will be left from Tom's ribbon?.
Me: Hmmm, let me think. I think this is the detailed solution:
The eight gifts require 1.5 meters / gift x 8 gifts = 12 meters of ribbon. So, Tom will be left with 15 meters - 12 meters = 3 meters of ribbon. Final answer: 3.
