## 1. Introduction to Percentages

### What is a Percentage?

A percentage is a way of expressing a number as a fraction of 100. It’s denoted by the symbol “%.” In essence, a percentage represents a part out of a whole.

Percentages are essential for simplifying comparisons between different quantities, especially when those quantities are part of a larger whole.

Understanding how to calculate percentages allows us to better grasp ratios, proportions, and many practical applications like calculating discounts, interest rates, and growth rates.

### Importance of Percentage Calculations
