Sean's truck has a 12-gallon gas tank. He just put 3 gallons of gas into the tank. Is this equivalent to a third of a tank? if not, what amount of gas is equivalent to a third of a tank?

3/12

Simplify it by dividing the numerator and denominator by 3. What do you get?

justins gas tank is 1/3 full. after he buys 2 gallons of gas, it is 1/2 full. how many gallons can justins tank hold?

To determine if 3 gallons of gas is equivalent to a third of the tank, we need to calculate what amount of gas would fill a third of the tank.

Since Sean's truck has a 12-gallon gas tank, a third of the tank can be calculated by dividing 12 by 3:

12 / 3 = 4.

So, a third of the tank would be 4 gallons of gas.

Since Sean just put 3 gallons of gas into the tank, it is not equivalent to a third of the tank. He still needs 1 more gallon to have a third of the tank filled.
