Calculate Percentages Now! →Understanding the Basics
A percentage represents a part of a whole, expressed as a fraction of 100. For instance, if you score 80 out of 100 on a test, that's an 80% score. Understanding this core concept is key to grasping more complex percentage calculations.
Three Common Percentage Problems
Most percentage-related questions fall into one of these categories:
- Finding a percentage of a number: What is P% of X? (e.g., What is 15% of 200?)
- Determining what percentage one number is of another: Y is what percent of X? (e.g., 30 is what percent of 150?)
- Calculating percentage increase or decrease: What is the percentage change from one number to another? (e.g., What is the percentage increase from 80 to 100?)
How to Calculate Number Percentage Manually
Let's look at how to solve each type of problem using formulas:
- Finding P% of X: Convert P% to a decimal (divide by 100), then multiply by X.
- Example: What is 20% of 50? 20/100 = 0.20. 0.20 * 50 = 10.
- Y is what percent of X: Divide Y by X, then multiply by 100.
- Example: 10 is what percent of 40? 10/40 = 0.25. 0.25 * 100 = 25%.
- Percentage change from A to B: ((B - A) / A) * 100.
- Example: Percentage change from 50 to 75? ((75-50)/50) * 100 = 50% increase.
