Section 1: Understanding the Basics of Percentages
What Is a Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It’s used to compare values and represent proportions.
10% means 10 out of every 100 parts.
Basic Formula
To find the percentage of a number:
Percentage (%) = (Part / Whole) × 100
Example
You scored 45 marks out of 60.
(45 / 60) × 100 = 75%
