Question

Over the weekend, Cedrick drove 45 1/4 miles. He used 2 1/2 gallons of gasoline. What is the unit rate for miles per gallon?

Answer 1

1
`(5)/(8)\\`

Explanation:

To find unit rates, divide the number in the numerator of the rate by the number in the denominator of the rate. A car traveled 344 miles on 16 gallons of gasoline. To find the miles per gallon (unit rate), divide the numerator of the rate by the denominator of the rate. 344/16 = 21.5 miles / gallon is the rate.

==>
`45(1)/(4) / 2 (1)/(2)`

==>
`(181)/(4) / (5)/(3) \\`

==>
`(181)/(4) * (2)/(5)`

==>
`(362)/(20)`

==> 18.1

==> 1
`(5)/(8)\\`
