Question

Subtract.

Susan began a trip with 18 1/2 gallons of gas in the gas tank of her car. If she used 17 3/4 gallons on the trip, how many gallons did she have left when she finished the trip?

1 1/4 gallons
1 2/4 gallons
1/2 gallons
3/4 gallons

Answer 1

18 1/2 -17 3/4
= 18.50 -17.75
= 0.75
= 3/4

The 4th selection is appropriate.
