Question

clarence began his pizza delivery route with 1/3 of a tank of gas in his car. when he made it back to the pizzeria, 1/4 of a tank of gas was left. how much gas did clarence use? write your answer as a fraction or as a whole or mixed number. tanks

Explanation:

Step1: Identify the initial and final gas amounts

Initial gas = $\frac{1}{3}$ tank, Final gas = $\frac{1}{4}$ tank.

Step2: Calculate gas used

Gas used = Initial gas - Final gas. So, $\frac{1}{3}-\frac{1}{4}$.
Find a common - denominator, which is 12. Then $\frac{1}{3}=\frac{4}{12}$ and $\frac{1}{4}=\frac{3}{12}$.
So, $\frac{4}{12}-\frac{3}{12}=\frac{4 - 3}{12}=\frac{1}{12}$.

Answer:

$\frac{1}{12}$
