A percentage is a mathematical concept that expresses a number as a portion out of 100. It's a universal way to compare values, proportions, and changes. For instance, if a survey shows that 60 out of 150 people prefer online shopping, converting that to a percentage makes it easier to interpret: 60 divided by 150 equals 0.4, or 40%. This simple conversion helps you understand and communicate data more effectively.
To calculate a percentage, divide the part (or smaller quantity) by the total (or whole), then multiply the result by 100. For example, say you earned 18 out of 24 points on a quiz. Divide 18 by 24 to get 0.75, then multiply by 100 to get 75%. That's your percentage score.
Percentages are everywhere—used to show changes in stock prices, track progress in projects, calculate taxes, and more. They simplify complex data into a relatable format, allowing you to compare different values on a consistent scale. Understanding percentages empowers smarter financial decisions, better data interpretation, and clearer communication.
