What is a percentage?

A percentage expresses a value as parts per hundred, making it easier to understand proportions and comparisons. The % symbol represents this relationship - for example, 75% means 75 parts out of 100. This universal mathematical concept helps us express everything from academic grades to financial calculations in a standardized way.

How do you calculate a percentage?

To find a percentage, divide your target number by the total and multiply by 100. For instance, to find what percentage 15 is of 60: divide 15 by 60 (0.25) and multiply by 100, giving you 25%. For percentage change, subtract the old value from the new value, divide by the old value, and multiply by 100.

Why percentages matter?

Percentages are essential tools in daily life, from calculating tips and discounts to understanding interest rates and investment returns. They help us make informed decisions about budgets, analyze business performance, track progress toward goals, and compare different quantities in a meaningful way.
