Word Problem: Two students are having a party. They want to make treat  bags for their guests. They want each bag to be identical  with nothing left over. They have 54 Silly Bands and 72  pieces of chewing gum to put in the bags. What is the  greatest number of goody bags they can make and how many  of each item will be in each treat bag?

Distributive Property (15 + 27) = 3 ( 5 + 9 ) (15 + 27) = 3 ( 5 + 9 ) Ex 1: ( 64 + 32 ) = _______________ Ex 2: ( 72 + 12 ) = _______________
