Suppose your gasoline tank holds 18 gallons of fuel. Your tank is currently 20% full. How many gallons of fuel do you need to add to fill the tank?

I believe the answer is 14.4 gallons of fuel.

To get the answer, I did x over 18 = 20% of 100. You cross-multiply to get 100x = 360. Divide each side by 100 to get x = 3.6. Subtract that from 18 gallons to get your answer.

If u have a coulculater do 18 times. 20 and that will give u the answer
