Guess the gas tank is 3/8 for when 3 gallons are added the tank is 9/16 pool how many gallons does the full tank hold

Answer 1

X is the number of gallons in the tank

9/16 - 3/8 = 9/16 - 6/16 = 3/16 <--- 3/16 was added to the tank

3 gallons = 3/16 X

3/1 * 16/3 = X

X= 16

The tank holds 16 gallons.

3/8 of 16 = 6 <--- the tank has 6 gallons, and 6/16 = 3/8

3 gallons is added, so that makes 9 gallons, or 9/16 of the tank.

The tank holds 16 gallons
