1. What is Percentage Calculation?

Percentage is a mathematical concept that represents a number or ratio as a fraction of 100. It's commonly used to express proportions, marks, discounts, and many other measurements in daily life.

2. How Does the Calculator Work?

The calculator uses the percentage formula:

Where:

• \( Obtained \) — Marks or points you've achieved
• \( Total \) — Maximum possible marks or points

Explanation: The formula converts the fraction of obtained marks to total marks into a percentage by multiplying by 100.

3. Importance of Percentage Calculation

Details: Percentage calculations are essential in academics for grading, in finance for interest rates, in statistics for data analysis, and in many other fields to compare relative quantities.

4. Using the Calculator

Tips: Enter obtained marks and total marks. Both values must be positive numbers, and obtained marks cannot exceed total marks.

5. Frequently Asked Questions (FAQ)

Q1: What if my obtained marks are more than total?
A: The calculator will show an error as obtained marks cannot exceed total marks in a valid percentage calculation.

Q2: How many decimal places does it show?
A: The calculator shows results rounded to 2 decimal places for precision.

Q3: Can I calculate percentage decrease?
A: Yes, if your obtained value is less than the original value, it will show the percentage decrease.

Q4: What's the difference between percentage and percentile?
A: Percentage is a ratio out of 100, while percentile indicates what percentage of values are below a certain value in a dataset.

Q5: Can I use this for other percentage calculations?
A: Yes, this works for any percentage calculation where you have a part and a whole, not just academic marks.
