Question

Royston's car had 15 1/5 gallons of gas at the start of the trip. During the trip, he stopped at a gas station and he refueled the car with 5 3/5 gallons. If the car consumed 17 4/5 gallons of gas during the trip, there are still ____________ gallons of gas remaining in the tank?

Answer 1

15 1/5 + 5 3/5 = 20 4/5

that is the total gallons of gas avalible

but they only used 17 4/5, so

20 4/5 - 17 4/5 = 3

so he only had 3 galons left after the trip

Answer 2

there are still 3 gallons of gas left.
