Question

Lena used a total of 3 5/6 gallons of gas while driving her car. Each hour she was driving, she used 7/9 gallons of gas. What was the total number of hours she was driving?

Answer 1

Explanation:

3 x 5/6 = 2.5 gallons of gas used

7/9 galllons per 1 hour

Hence if she used 2.5 gallons,

2.5 ÷ 7/9 =

`3 (3)/(14) hours`
