How Percentages Work
The word "percent" means "per hundred." So 20% means 20 out of every 100. The formula is: Result = (Percentage / 100) × Amount. For 20% of 300: (20 / 100) × 300 = 60.

Mental Math Tip
To calculate 20% quickly: find 10% first (30), 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 20% discount followed by another 20% discount is NOT 40% off. The second discount applies to the already-reduced price. Also, percentage increase and percentage points are different: going from 20% to 40% is a 20 percentage point increase but a 100% relative increase.
