Question

Arrange the following in descending order:
$\frac{2}{9},\frac{2}{3},\frac{2}{81}$

Answer 1

$\Rightarrow \frac{2}{9},\frac{2}{3},\frac{2}{81}$

Finding out their LCM we get, [Ref. image]

$\therefore$ LCM will be

$\therefore \frac{2}{9}=\frac{18}{81},\frac{2}{3}=\frac{54}{81},\frac{2}{81}$.

$\therefore \frac{2}{81}<\frac{18}{81}<\frac{54}{81}$

In descending order

$\Rightarrow \frac{2}{3}>\frac{2}{9}>\frac{2}{81}$
