Jesse drove with his car 18 2/5 miles with 4/5 gallon of gas. At that rate, what’s the miles per gallon rate?

Given:
[tex]18\frac{2}{5}\text{ = }\frac{92}{5}\text{ miles}[/tex]to 4/5 gallon of gas.
To find the rate, we have 92/5 divided by 4/5; then:
[tex]\frac{92}{5}\div\frac{4}{5}\text{ = }\frac{92}{4}=23\text{ miles per gallon}[/tex]
