Question

Write your answer as a mixed number in simplest form.

Answer 1

Answer: 5 & 7/10 hours

Work Shown:

4 & 3/4 = 4 + 3/4 = 4 + 0.75 = 4.75

total gas used = (gas used per hour)*(number of hours)

4.75 = (5/6)x

(5/6)*x = 4.75

x = (6/5)*4.75

x = 5.7

x = 57/10

x = (50+7)/10

x = 50/10 + 7/10

x = 5 + 7/10

x = 5 & 7/10
