Question

PLEASE HELP!

A pump currently contains 4 7/8 gallons of water but needs to be filled to capacity. The capacity of the pump is 9 5/8 gallons.

How much more water is needed to completely fill the pump?
Express your answer in simplest mixed-number form.

Answer 1

9 5/8 gallon max capacity - 4 7/8 gallons currently in tank = gallons needed
8 13/8 - 4 7/8 = 4 6/8 gallons
simplify to 4 3/4 gallons
