40 miles per gallon = 40 miles per 1 gallon = 40 miles / 1 gallon. If he can drive 40 miles on 1 gallon of gas, how many miles can he drive on 8.9 gallons of gas?
40 miles * 8.9 gallons = 356 miles
----------
1 gallon
The "gallons" in the top and bottom of the resulting fraction cancel each other out, leaving you with a number of miles.
