Decimal to Percent

Converting a decimal number to percent means to express it per 100, as ‘Percent’ or ‘%’ means per 100.

We can easily turn a decimal to a fraction with the help of a calculator or converter. However, we might not have a converter handy.

Steps

So, let us take 0.25 and change it to percent as illustrated in the figure below.

1. Multiply the decimal with 100.
2. Move the decimal point 2 places to the right. Add a zero right after the decimal point. It can be done mentally also without a pen and paper.
3. Put a ‘%’ sign after the result. Remove the zero if there is no following digit.

Let us solve some examples involving the above concept.
