What is 10% of 500?
Calculate Any Percentage
Step-by-Step Solution
- Write 10% as a decimal: 10 ÷ 100 = 0.1
- Multiply: 0.1 × 500 = 50
Formula: Percentage × Amount ÷ 100 = Result
How Percentages Work
The word "percent" means "per hundred." So 10% means 10 out of every 100. The formula is: Result = (Percentage / 100) × Amount. For 10% of 500: (10 / 100) × 500 = 50.
Real-World Examples
Shopping: a 10% discount on a $500 item saves you $50. Tips: 10% tip on a $500 bill is $50. Finance: 10% annual return on a $500 investment earns $50 per year. Tax: 10% tax rate on $500 income means $50 in taxes.
Mental Math Tip
To calculate 10% quickly: find 10% first (50), 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 10% discount followed by another 10% discount is NOT 20% off. The second discount applies to the already-reduced price. Also, percentage increase and percentage points are different: going from 10% to 20% is a 10 percentage point increase but a 100% relative increase.
