Question

If a car will go 108 miles on a 6 gallon of gasoline in city driving. What is the rate in miles per gallon.

Answer 1

To find the rate in miles per gallon, divide the number of miles by the number of gallons of gasoline:

$\frac{108\; \text{miles}}{6\; \text{gallons}}$

Reduce the fraction by 6:

$\frac{108}{6}=18\text{ miles per gallon}$

The rate in miles per gallon is 18.
