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
