Question

Find the sum or difference of the following:
$\frac{2}{11} + \frac{2}{7}$

Open in App

Solution

Consider
$\frac{2}{11} + \frac{2}{7} = \frac{2 \times 7}{11 \times 7} + \frac{2 \times 11}{7 \times 11} = \frac{14}{77} + \frac{22}{77} = \frac{14 + 22}{77} = \frac{36}{77}$
Hence, the sum of $\frac{2}{11} + \frac{2}{7}$ is $\frac{36}{77}$
