Question

Add the following rational numbers:

(a) $\frac{2}{7}$ and $\frac{3}{7}$

(b) $\frac{-4}{11}$ and $\frac{7}{11}$

Answer 1

$\left(a\right)\frac{2}{7}+\frac{3}{7}$

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

$=\frac{5}{7}$

$\left(b\right)\frac{-4}{11}+\frac{7}{11}$

$\Rightarrow \frac{-4+7}{11}$

$=\frac{3}{11}$
