How Percentage Calculation Works
To calculate a percentage, multiply the number by the percentage and divide by 100. For example, 10% of 500 equals 50.
Basic Formula:
Percentage Value = (Number × Percentage) ÷ 100
Common Use Cases:
- Sales & Discounts: Calculate how much you save with a 20% discount
- Tips & Gratuity: Calculate 15% or 20% tip at restaurants
- Tax Calculations: Determine tax amounts on purchases
- Grade Scoring: Convert marks to percentages
- Financial Planning: Calculate savings goals and investment returns
Examples:
Example 1: What is 25% of 200?
Calculation: (200 × 25) ÷ 100 = 50
Example 2: What is 15% of 80?
Calculation: (80 × 15) ÷ 100 = 12
Example 3: What is 5% of 1000?
Calculation: (1000 × 5) ÷ 100 = 50
