1. What is Percentage Calculation?

Percentage calculation determines what portion a percentage represents of a given number. It's a fundamental mathematical operation used in various fields including finance, statistics, and everyday calculations.

2. How Does the Calculator Work?

The calculator uses the percentage formula:

Where:

• \( \text{Percent} \) — The percentage value (e.g., 25 for 25%)
• \( \text{Number} \) — The base number you want to calculate the percentage of

Explanation: The formula converts the percentage to a decimal (by dividing by 100) and then multiplies it by the base number to get the result.

3. Importance of Percentage Calculation

Details: Percentage calculations are essential for understanding proportions, discounts, interest rates, statistical data, and many real-world applications where relative values matter more than absolute numbers.

4. Using the Calculator
