Answer
$1\frac{1}{5}$
Work Step by Step
Fractions are ready to add if they are $like$
fractions (page 198).
$\frac{9}{10}$+$\frac{3}{10}$ = $\frac{9 + 3}{10}$ = $\frac{12}{10}$
Add the numerators
$12$ is the sum of the numerators
$10$ is the same denominator
$\frac{12}{10}$ is not in $lowest$ $terms$ (page 132).
Write the answer in lowest terms: $\frac{12\div2}{10\div2}$ = $\frac{6}{5}$
$\frac{6}{5}$ is not simplified because it is an $improper fraction$ (page 121).
Simplify the answer. Write the improper fraction $\frac{6}{5}$ as a mixed number.
Divide $6$ by $5$
$6$ $\div$ $5$ = one whole with $\frac{1}{5}$ left over.
$1\frac{1}{5}$
