At its core, a percentage is a way to express a number as a fraction of 100. It represents a part of a whole. The term "percent" literally means "per hundred." Understanding this fundamental concept is crucial for mastering percentage calculations.
Three Common Percentage Problems
Most percentage problems fall into one of three categories:
- Finding the percentage of a number: What is X% of Y? (e.g., What is 15% of 200?)
- Finding what percentage one number is of another: X is what percent of Y? (e.g., 30 is what percent of 150?)
- Calculating percentage increase or decrease: From X to Y, what is the percentage change? (e.g., From 80 to 100, what is the percentage increase?)
Solving Percentage Problems Manually
While calculators can quickly provide answers, understanding the manual calculation process is beneficial:
- Finding X% of Y: Convert X% to a decimal (divide by 100) and multiply by Y.
- Finding what percent X is of Y: Divide X by Y and multiply by 100.
- Calculating percentage change: Find the difference between the new value (Y) and the original value (X), divide by the original value (X), and multiply by 100.

Beyond Basic Calculations
Percentages are used in many contexts, including calculating tips, understanding financial growth, and analyzing statistical data. Mastering percentage calculations empowers you to make informed decisions in various aspects of life.
Understanding Percentage Difference vs. Percentage Change
It's important to distinguish between percentage difference and percentage change. Percentage difference compares two values, while percentage change tracks the change in a single value over time.
For example, consider this handy tip found on Reddit: "A fun percentage trick I learned very late is that n% of m is the same as m% of n (e.g. 40% of 20 == 8 == 20% of 40)".
