We normally use the % sign as the percent indicator, but we also call it by pct. It indicates that 10% is the same as 10%, 10pct, 0.10, 10/100, or 10 hundredths. That's all there is to it, and this % calculator is a tool for working with decimal fractions and percentages.

Example:

Suppose 500 is the total score obtained by you in the examination out of 2000 marks, then you divide 500 by 2000, and then multiply it by 100.

Percentage of marks =(500/2000) x 100

Percentage= 0.25 x 100

Therefore, the percentage of marks obtained is 25%.
