Fill in the blank :

$0.2$ as per cent $=$ …………….. .

It is given that,

$0.2$ as per cent $=$ …………….. .

To convert fraction to percentage , $0.2$ is multiplied to $100\%$.

So, $0.2\times 100\%$

Note : If a decimal number is multiplied by $100$, then the decimal point is moved from left to right by $2$ places.

As it contains one digit after decimal point , we need to include a zero beside the existing digit .

$0.2\times 100\%$ $=$ $20\%$

Hence, the answer for the given blank is $20\%$.
