To do: To fill the blank.

Solution:

As given $\frac{2}{7}=\frac{8}{\square}$

Let $x$ is the denominator in R.H.S. fraction,

then it becomes, $\frac{2}{7}=\frac{8}{x}$

On cross multiplication,

$\Rightarrow 2x=56$

$\Rightarrow x=\frac{56}{2}$

$\Rightarrow x=28$

$\therefore \frac{2}{7}=\frac{7}{28}$
