For every 3 packages that Marcella wraps,she uses 1/2 of a roll of wrapping paper.If she uses 2 1/2 rolls of wrapping paper,how many packages has she wrapped?

Answer 1

2 1/2 rolls equals 5 halves. A half roll gets used every three packages. So Marcella will wrap 15 packages to get through 2 1/2 rolls.

Answer 2

Well, isn't that just a happy little math problem? If Marcella uses 1/2 a roll of wrapping paper for every 3 packages, and she used 2 1/2 rolls in total, that means she wrapped 15 packages in all. That's a lot of love and care put into each and every one!
