Question

Covert the following fractions into like fractions.
$\frac{2}{5},\frac{3}{10}$ and $\frac{7}{20}$

Answer 1

$\frac{2}{5},\frac{3}{10}$ and $\frac{7}{20}$

LCM of $5,10$ and $20=20$

Therefore,

$\frac{2}{5}\times \frac{20}{20}=\frac{8}{20}$

$\frac{3}{10}\times \frac{20}{20}=\frac{6}{20}$

$\frac{7}{20}\times \frac{20}{20}=\frac{7}{20}$

Hence $\frac{2}{5},\frac{3}{10}$ and $\frac{7}{20}$ is same as $\frac{8}{20},\frac{6}{20}$ and $\frac{7}{20}$.
