Gwen was using a container to fill up a fishbowl. The container held 1/7 of a gallon of water and filled 1/5 of the fishbowl. At this rate, how many containers will it take to fill the fishbowl?
The question asks how many containers will it take to fill the fish tank if one fills 1/5... Well, 5/5 is a whole so it will take 5 containers to fill the whole tank.
