Answer 2

$LHS = \Big(\frac{162}{343}\Big) \times \Big(\frac{49}{81}\Big)$

$= \Big(\frac{2\times \cancel{81}}{7\times \cancel {49}}\Big) \times \Big(\frac{\cancel {49}}{\cancel {81}}\Big)$

$= \frac{2}{7} \\= RHS$

Therefore.,

$\red{ \Big(\frac{162}{343}\Big) \times \Big(\frac{49}{81}\Big)}\green { = \frac{2}{7}}$
