Supporting grades: 5

Description: Sal solves a US customary volume word problem involving pints and gallons. Created by Sal Khan and Monterey Institute for Technology and Education.

You may or may not know how many pints there are per gallon, so let's just go straight to quarts first, and then from quarts we can go to gallons.
