What is a Percentage?

A percentage is a way to express a number as a fraction of 100, denoted by the symbol "%". It represents a part of a whole, making it easier to compare proportions. For example, 50% means 50 out of 100.

How Do You Calculate a Percentage?

To calculate a percentage, you typically divide the part (the smaller value) by the whole (the larger value), and then multiply the result by 100. This gives you the percentage value as a number between 0 and 100.

Formula: (Part ÷ Whole) × 100
For example: If you score 45 out of 50, the percentage is (45 ÷ 50) × 100 = 90%.

Why Percentages Matter?

Percentages are crucial for understanding proportions and changes. They are used in finance, education, health, and everyday life for tasks like calculating interest, analyzing data, or understanding performance. Percentages simplify comparisons and help make informed decisions.
