Question

Gina bought 6 containers of yogurt for $4. how many containers of yogurt could gina buy for $12?

Answer 1

6 containers =    4$
  X containers  = 12 $

When you cross multiply , it will be 4X = 72

therefore X= 72/4= 18 . 

Or just use your logic for that answer , 12 /4 is 3 right? 
then multiply 6 by 3
