Question

Ben used 10 1/2 gallons to drive 4 3/4 hours. How many gallons did Ben use in 1 hour?

Answer 1

About 2.2 gallons

Explanation:

Create the following proportion:

`(10.5)/(4.75)` =
`(x)/(1)`

Cross multiply.

10.5 x 1 = 10.5

4.75 x X = 4.75x

4.75x = 10.5

Divide both sides by 4.75x.

10.5/4.75 = 2.2
