Fill in the blank :

If $\frac{12}{16}$means $x\%$ then $x=...............$

It is given that, $\frac{12}{16}$ means $x\%$

So, $\frac{12}{16}$$=$$x\%$

it implies,

$\frac{12}{16}$ $=$$\frac{x}{100}$ ( on dividing $12$ and $16$by their common factor $4$, we get $\frac{3}{4}$)

$\frac{3}{4}=\frac{x}{100}$

transpose $100$ to L.H.S

$\frac{3}{4}\times 100=x$

Rewrite as

$x=\frac{3}{4}\times 100$

( on dividing $100$ by $4$, we get $25$)

$x=3\times 25$

$x=75$.

Hence, The value of $xis75$.
