Percentage is a way of expressing a number as a fraction of 100. It is often used to compare quantities and to express proportions.

To calculate the percentage of a number, you can use the following formula:

Percentage = (Part/Total) * 100

For example, if you want to find 25% of 80, you would use the formula:

Percentage = (25/100) * 80 = 0.25 * 80 = 20

To convert a percentage to a decimal, you can simply divide the percentage by 100. For example, 25% as a decimal would be 0.25.

To convert a percentage to a fraction, you can write the percentage as a fraction with a denominator of 100, and then simplify if possible. For example, 25% as a fraction would be 25/100, which simplifies to 1/4.

Percentages are used in many real-life situations, such as calculating discounts, expressing interest rates, and understanding proportions in data analysis.
