1. What is Percentage Calculation?

Percentage calculation determines what portion a number (part) is of another number (whole), expressed as a value out of 100. It's a fundamental mathematical concept used in various real-world applications.

2. How Does the Calculator Work?

The calculator uses the percentage formula:

Where:

• Part — The portion of the whole you're measuring
• Whole — The total or reference amount
• 100 — Converts the fraction to a percentage

Explanation: The formula divides the part by the whole to get a decimal, then multiplies by 100 to convert to a percentage.

3. Importance of Percentage Calculation

Details: Percentage calculations are essential in finance (interest rates), statistics (data analysis), shopping (discounts), academics (grades), and many other fields.

4. Using the Calculator

Tips: Enter both part and whole as positive numbers. The whole must be greater than zero. The result shows what percentage the part is of the whole.

5. Frequently Asked Questions (FAQ)

Q1: What if my part is larger than the whole?
A: The calculator will show a percentage greater than 100%, indicating the part exceeds the whole.

Q2: Can I calculate percentage decrease?
A: Yes. If the part represents a decrease from the whole, the result shows the percentage decrease.

Q3: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while this calculates relative proportion.

Q4: What about percentage of percentage?
