I'll do city.

You can follow up with highway.

City milease is 16 miles per gallon.

Since 1 gallon = 128 ounces, this means that:

City mileage is 16 miles per 128 ounces.

In order to find out how many miles per ounce, you have to divide numerator and denominator by 128 to get:

City milease is .125 miles per ounce.

Your answer for city mileage is that it equals to .125 miles per ounce.

Your answer for highway mileage is that it equals to .15625 miles per ounce.
