Percentage is a way of expressing a number as a fraction of 100. It is used to compare different amounts or to show how much of something has changed. It is a useful tool for comparing different values, such as prices, profits, or rates of change.

A Percentage Calculator is a tool used to calculate a percentage of a given number. It can be used to calculate the percentage of a number, the percentage of a total, or the percentage change between two numbers.

To calculate a percentage, start by converting the percentage number to a decimal by dividing it by 100. Then, multiply the decimal by the whole number that you want to find the percentage of. Finally, to find the answer, multiply the resulting decimal by 100. For example, to find 25% of 80, start by converting 25% to a decimal by dividing it by 100: 25/100 = 0.25. Then, multiply 0.25 by 80: 0.25 x 80 = 20. Finally, to find the answer, multiply 20 by 100: 20 x 100 = 2000. Therefore, 25% of 80 is 2000.
