1. What is a Percentage Calculator for Marks?

Definition: This calculator computes the percentage score based on marks obtained out of total marks.

Purpose: It helps students, teachers, and professionals quickly determine percentage scores for tests, exams, or evaluations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \% \) — Percentage score
• \( Marks \) — Marks obtained (unitless)
• \( Total \) — Total possible marks (unitless)

Explanation: The marks obtained are divided by total marks and multiplied by 100 to convert to percentage.

3. Importance of Percentage Calculation

Details: Percentage scores provide a standardized way to compare performance across different tests or evaluation systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Can I use decimal values for marks?
A: Yes, the calculator accepts decimal values for precise calculations.

Q2: What if I get more marks than the total?
A: The calculator won't compute if marks exceed total, as this is mathematically impossible.

Q3: How is this different from grade calculation?
A: This calculates raw percentage only. Grading systems may apply different scales to percentages.

Q4: Can I calculate percentage decrease with this?
A: No, this is for score percentage only. Use a different calculator for percentage changes.

Q5: Why multiply by 100 in the formula?
A: Multiplying by 100 converts the decimal fraction (0-1) to a percentage (0-100%).
