Question

Solve : $\frac{7}{10}+\frac{2}{5}+\frac{3}{2}$

Answer 1

Given expression: $\frac{7}{10}+\frac{2}{5}+\frac{3}{2}$

Since, $10$ is multiple of $5$ and $2$.

$\Rightarrow$ LCM of $10,5$ and $2$ is $10$.

$\Rightarrow \frac{7}{10}+\frac{2}{5}+\frac{3}{2}$

$=\frac{7}{10}+(\frac{2}{5}\times \frac{2}{2})+(\frac{3}{2}\times \frac{5}{5})$

$=\frac{7}{10}+\frac{4}{10}+\frac{15}{10}$

$=\frac{7+4+15}{10}$

$=\frac{26}{10}$

$=\frac{13}{5}$

$\therefore \frac{7}{10}+\frac{2}{5}+\frac{3}{2}=\frac{13}{5}$
