Write an equation for the problem. Then solve the equation.

There are 18 gallons of water in the tank. The tank is three-fourths full. How many gallons of water g can the tank hold?
A. 12
B. 14
C. 22
D. 24

1 answer

Let's let "g" be the amount of water the tank can hold, in gallons.

Since the tank is currently three-fourths full, we know that there are 3/4 * g gallons of water in the tank.

And we also know that there are 18 gallons of water in the tank. So we can set up the equation:

3/4 * g = 18

To solve for "g", we can start by multiplying both sides by the reciprocal of 3/4, which is 4/3:

g = 18 * (4/3)

g = 24

So the tank can hold 24 gallons of water.

Therefore, the correct option is D. 24.
