A percentage is simply a way to express a number as a fraction of 100. The word "percent" means "per hundred." So, 25% is equivalent to 25/100, or 0.25. Understanding this core concept is key to mastering percentage calculations. If you'd like to learn more about percentages generally, see our comprehensive guide to percentages.
The Basic Formula
The formula for finding a percentage of a whole number is straightforward:
(Percentage / 100) * Whole Number = Result
Let's break it down:
- Percentage: The percentage you want to find (e.g., 15%).
- Whole Number: The total number you're taking a percentage of (e.g., 200).
- Result: The answer you're looking for.
Step-by-Step Example
Let's say you want to find 15% of 200.
- Convert the percentage to a decimal: Divide 15 by 100, which gives you 0.15.
- Multiply the decimal by the whole number: 0.15 * 200 = 30.
- The result is the percentage of the whole number: 15% of 200 is 30.
