The calculator uses the percentage formula:

Where:

• Part — The portion of the whole you want to measure
• Whole — The total or complete amount

Q3: How is percentage different from fraction?
A: A fraction represents a part of a whole, while a percentage standardizes this as parts per hundred.

Q4: What are common uses of percentages?
A: Test scores, financial calculations (interest, discounts), statistics, probability, and many real-world measurements.

Q5: How to calculate percentage change?
A: Percentage change = [(New Value - Old Value)/Old Value] × 100
