What is a Percentage?

In mathematics, a percentage is a number or ratio that represents a fraction of 100. It is commonly used to compare values, express proportions, and calculate changes in numbers. The percentage symbol (%) is used to denote percentages.

For example:

35% is equivalent to 0.35 in decimal form.

Similarly, 50% can be written as:

50% = 50/100 = 0.5

How to Calculate a Percentage?

To calculate a percentage, multiply the given number by the percentage and then divide by 100.

Formula:

X% of Y = (X / 100) × Y

Example:

25% of 200 = (25 / 100) × 200 = 50

Percentage Calculator Formulas

Your percentage calculator supports the following calculations:

1. What is X% of Y?

This calculation finds the percentage value of a number.

Formula:

P% × V1 = V2

15% of 300 = (15 / 100) × 300 = 45

2. X is What % of Y?

This finds what percentage one number is of another.

Formula:

(X / Y) × 100
