Reese's car has a 12 gallon gas tank. Right now, his gas gauge reads 1/3 full. If he buys 3 gallons of gas, what will the new reading on the gas gauge be?

The new reading on the gas gauge will be will be 7/12 full

Step-by-step explanation:

From the question

Reese's car has a 12 gallon gas tank. Right now, his gas gauge reads 1/3 full.

Hence, the quantity of gas in the tank is currently:

12 gallon × 1/3

= 4 gallons

If he buys 3 gallons of gas

Total amount of gas = 4 gallons + 3 gallons

= 7 gallons of gas

The new reading on the gas gauge will be:

4 gallons of gas = 1/3

7 gallons of gas = x

Cross Multiply

4 gallons × x = 7 gallons × 1/3

x = 7 gallons × 1/3/4

x = 7/3 ÷ 4

x = 7/3 × 1/4

x = 7/12

The new reading on the gas gauge will be will be 7/12 full
