Add: $\frac{7}{10}$ and $\frac{2}{15}$
✓
Answer
Given: $\frac{7}{10}$ and $\frac{2}{15}$
$\frac{7}{10}+\frac{2}{15}$
$LCM$ of $10$ and $15$ is $30$,
so we will convert each fraction into an equivalent fraction with denominator $30$.
$=\frac{7\times3}{10\times3}+\frac{5\times2}{15\times2}$
$=\frac{21}{30}+\frac{4}{30}$
$=\frac{21+4}{30}$
$=\frac{25}{30}$
$\frac{7}{10}+\frac{2}{15}$
$LCM$ of $10$ and $15$ is $30$,
so we will convert each fraction into an equivalent fraction with denominator $30$.
$=\frac{7\times3}{10\times3}+\frac{5\times2}{15\times2}$
$=\frac{21}{30}+\frac{4}{30}$
$=\frac{21+4}{30}$
$=\frac{25}{30}$
