Question

Find the average of the rational numbers $\frac{4}{5},\frac{2}{3},\frac{5}{6}$.

Answer 1

average of rational numbers =$\frac{4}{5},\frac{2}{3},\frac{5}{6}$.

$\Rightarrow \frac{\frac{4}{5}+\frac{2}{3}+\frac{5}{6}}{3}$ $=\frac{24+20+25}{30\times 3}$

Average $\Rightarrow \frac{69}{90}=\frac{23}{30}$
