Question

Find the sum of $\frac{8}{13}$ and $\frac{3}{11}$ .

Open in App

Solution

Given, $\frac{8}{13}$ and $\frac{3}{11}$
Sum $= \frac{8}{13} + \frac{3}{11} = \frac{8 \times 11}{13 \times 11} + \frac{3 \times 13}{11 \times 13} = \frac{88}{143} + \frac{39}{143}$
$= \frac{88 + 39}{143}$
$= \frac{127}{143}$
Hence, the sum of $\frac{8}{13}$ and $\frac{3}{11}$ is $\frac{127}{143}$
