Question

in the morning, jerry drove to the store and used 2 gallons of gas. in the afternoon, he drove to the movie theater and used 1/5 of a gallon of gas. how much gas did jerry use in all? write your answer as a fraction or as a whole or mixed number. gallons

Explanation:

Step1: Convert whole - number to fraction

We know that $2=\frac{2\times5}{5}=\frac{10}{5}$.

Step2: Add the two fractions

We add the gas used in the morning and afternoon. $\frac{10}{5}+\frac{1}{5}=\frac{10 + 1}{5}=\frac{11}{5}$.

Step3: Convert to mixed - number

$\frac{11}{5}=2\frac{1}{5}$.

Answer:

$2\frac{1}{5}$
