The bailey family started a trip with a tank of 7/8 full of gas. the family finished the trip with a tank 1/4 full of gas. if no gas was added to the tank how much gas was used for the trip.
a.5/8
b3/4
c.9/8
d.3/2

The answer is A.5/8.

Why?

Multiply 1/4 with 2/2 to get the same denominator as 7/8, 8. That will yield 2/8.Then, simply subtract 2/8 from 7/8 (7/8 - 2/8), and that equals 5/8.

Hope this helps!

The answer would end up being A. 5/8 because if you subtract 1/4 from 7/8 you would have to multiply the 1/4 by 2 to give you 2/8 so it can be subtracted from 7/8 because they have to have the same denominator and then you end up with a total of 5/8 gas was used for the trip
