How Percentages Work
The word "percent" means "per hundred." So 75% means 75 out of every 100. The formula is: Result = (Percentage / 100) × Amount. For 75% of 100: (75 / 100) × 100 = 75.
Real-World Examples

Mental Math Tip
To calculate 75% quickly: find 10% first (10), then adjust. 5% is half of 10%. 20% is double 10%. 1% is 10% divided by 10. Combine these building blocks for any percentage without a calculator.
Common Mistakes
Successive discounts do not add up. A 75% discount followed by another 75% discount is NOT 150% off. The second discount applies to the already-reduced price. Also, percentage increase and percentage points are different: going from 75% to 150% is a 75 percentage point increase but a 100% relative increase.
