Calculate Percentages Instantly →Understanding Percentages
At its core, a percentage is a way to express a number as a fraction of 100. The term "percent" literally means "per hundred." So, 25% simply means 25 out of every 100. Mastering this concept is the first step in learning how to calculate a percentage.
Calculating the Percentage of a Number
The most common type of percentage problem involves finding what a certain percentage of a number is. For example, you might want to know what 15% of 200 is. Here's the breakdown:
- Convert the percentage to a decimal: Divide the percentage by 100. So, 15% becomes 0.15 (15 / 100 = 0.15).
- Multiply the decimal by the number: Multiply 0.15 by 200 (0.15 * 200 = 30).
Therefore, 15% of 200 is 30.
Other Types of Percentage Problems
While finding a percentage of a number is common, there are other percentage calculations you might encounter:
- Finding what percentage one number is of another: For example, what percentage is 30 of 150? (30 / 150) * 100 = 20%. So, 30 is 20% of 150.
- Calculating percentage increase or decrease: If a value changes from 80 to 100, what's the percentage increase? [(100 - 80) / 80] * 100 = 25%. There's a 25% increase.
