Ms. Johnson had 3/4 of a tank of gas when she started a trip. When she arrived home, she had 1/8 of a tank left.What fraction of a tank of gas was used during the trip
3/4 - x = 1/8 x is the fraction used 3/4 - 1/8 = x (8)3/4 - 1/8(4) = x 24/32 - 4/32 = x 20/32 = x Simplify 20/32 (/4) = 5/8 Hence she used 5/8 of the tank To check the answer 3/4 - 5/8 = 1/8
