A 14.5-gallon gasoline tank is 3/4 full. How many gallons will it take to fill the tank? Would I use Addition, Subtraction, Multiplication, or Division?

It will take 3.7 gallons of gasoline to fill up the tank. You will need to use division.

Step-by-step explanation:

You take the full 14.5 gallons and divide it by 4 that will get you the last fourth of a whole to fill up the gallon. When you divide, you get exactly 3.625 but rounding up to 3.7 will completely fill up the tank.
