Question
Add: $\frac{4}{5}$ and $\frac{7}{15}$
✓
Answer
Given: $\frac{4}{5}$ and $\frac{7}{15}$
$\frac{4}{5}+\frac{7}{15}$
$LCM$ of $5$ and $15$ is $15$,
so we will convert each fraction into an equivalent fraction with denominator $15$.
$=\frac{4\times3}{5\times3}+\frac{7\times1}{15\times1}$
$=\frac{12}{15}+\frac{7}{15}$
$=\frac{12+7}{15}$
$=\frac{19}{15}$
$\frac{4}{5}+\frac{7}{15}$
$LCM$ of $5$ and $15$ is $15$,
so we will convert each fraction into an equivalent fraction with denominator $15$.
$=\frac{4\times3}{5\times3}+\frac{7\times1}{15\times1}$
$=\frac{12}{15}+\frac{7}{15}$
$=\frac{12+7}{15}$
$=\frac{19}{15}$
