question: John packs M&M in small bags to eat.  He buys 3 large bags weighing 10 ounces each.  If an ounce of M&M has 30 M&M in it how many small bags can he make if he puts 10 in each small bag?
answer: He bought 3*10=<<3*10=30>>30 ounces of M&M
  That means he got 30*30=<<30*30=900>>900 M&Ms
  So he can make 900/10=<<900/10=90>>90 bags
