Question

A generator runs for 2 1/2 h and uses 4 3/8 gal of fuel. How many gallons of fuel did the generator use each hour? Enter your answer as a mixed number in simplest form in the box.

Answer 1

1
`(3)/(4)` gallons per gour

divide number of gallons used by running time

4
`(3)/(8)`÷ 2
`(1)/(2)`

change mixed numbers to improper fractions

`(35)/(8)` ÷
`(5)/(2)`

leave the first fraction, change division to multiplication, turn the second fraction upside down

=
`(35)/(8)` ×
`(2)/(5)`

= ( 35 × 2 ) / (8 × 5 ) =
`(7)/(4)` = 1
`(3)/(4)`
