a 14.5 gas tank is 3/4 full. How many gallons will it take to fill?

Please help me set this up. Thanks!!!

a full tank is 4/3 as much as a 3/4 tank.

So, 4/3 * 14.5

To calculate how many gallons it will take to fill a 14.5-gallon gas tank that is 3/4 full, you can follow these steps:

Step 1: Find out how many gallons are currently in the tank.
To do this, multiply the capacity of the tank (14.5 gallons) by the fraction that represents how full it is (3/4):
14.5 gallons * (3/4) = 10.875 gallons

Step 2: Calculate how many gallons it will take to fill the tank completely.
Since the tank is already 10.875 gallons full, subtract this amount from the total capacity of the tank:
14.5 gallons - 10.875 gallons = 3.625 gallons

Therefore, it will take 3.625 gallons to fill the 14.5-gallon tank completely.
