1. What is a Percentage Calculator?

Definition: This calculator computes the percentage based on marks obtained and total marks.

Purpose: It helps students, teachers, and professionals quickly determine percentages for grades, statistics, or any proportional calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Percentage result
• Marks — Value obtained (must be ≤ total)
• Total — Maximum possible value

Explanation: The marks are divided by the total to get a decimal value, which is then multiplied by 100 to convert to a percentage.

3. Importance of Percentage Calculation

Details: Percentage calculations are fundamental in education, finance, statistics, and many real-world applications to understand proportions and comparisons.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What if my marks are higher than the total?
A: The calculator will not compute results if marks exceed total, as this is mathematically invalid for percentage calculation.

Q2: How many decimal places does it show?
A: Results are displayed with 2 decimal places for precision.

Q3: Can I calculate percentage decrease?
A: Yes, by entering the decreased value as marks and original value as total.

Q4: What if I enter zero for total marks?
A: The calculator requires total marks to be greater than zero.

Q5: How is this different from percentage points?
A: This calculates simple percentage, while percentage points measure the difference between two percentages.
