What is a Percentage?

A percentage is a way of expressing a fraction or a proportion out of 100. It is denoted by the symbol "%". Percentages are used to compare quantities, express ratios, and analyze data in various fields such as finance, mathematics, and statistics.

How to Calculate Percentages

Calculating percentages may seem daunting at first, but with a clear understanding of the formulas involved, it becomes a straightforward process. Let's explore the different methods of calculating percentages.

Percentage Formula

The basic percentage formula is simple yet powerful. To calculate a percentage, divide the part by the whole and multiply the result by 100. The formula can be expressed as:

Percentage = (Part / Whole) * 100

Calculating Percentage Increase or Decrease

Percentage increase or decrease is often used to analyze changes over time. To calculate the percentage increase or decrease, use the following formula:

Percentage Change = ((New Value - Old Value) / Old Value) * 100

Finding the Percentage of a Number

Sometimes, you may need to find the percentage of a number. To do this, multiply the number by the percentage and divide the result by 100. The formula can be written as:

Percentage of a Number = (Number * Percentage) / 100
