This is a 5th grade math problem in the section titled fraction word problems. Any help would be greatly appreciated!

The tub is capable of holding 32 gallons, but is only (4/7) full.

If N is the number of gallons of water in the tub then

N = (4)*(32 gallons)/7 = (128/7) gallons or 18 and (2/7) gallons or 18.286 gallons depending on how you are supposed to show your answer.
