Question

Solve the given proportion $2:\pi =x:\left(\frac{22}{7}\right)$

Answer 1

$2:\pi =x:\frac{22}{7}$

$\Rightarrow \frac{2}{\pi }=\frac{x}{\frac{22}{7}}$

$\Rightarrow \frac{2}{\pi }=\frac{7x}{22}$(cross multiply)

$\Rightarrow 7x\times \pi =22\times 2$

$\Rightarrow x=\frac{44}{7\pi }$

$\pi$ is not $\frac{22}{5}$
