Understanding the Concept
Percent means 'per hundred' - a percentage is a fraction with 100 as the denominator. Percentages are used everywhere: discounts, taxes, statistics, grades, and data analysis.
Key Percentage Concepts
- 1Percent = per hundred: 45% = 45/100 = 0.45
- 2Converting between fractions, decimals, and percentages
- 3Finding a percent of a number (multiply by decimal form)
- 4Percent increase and decrease calculations
- 5Finding what percent one number is of another
- 6Working with percentages greater than 100%
⚠️ Common Mistakes to Avoid
- •Confusing % increase vs new total
- •Moving decimal wrong way when converting
- •Forgetting to convert % to decimal before calculating
- •Adding percentages incorrectly in successive changes
- •Confusing percent OF vs percent MORE/LESS
🌍 Real-World Applications

✨ Expert Study Tips
To find 10%, move decimal one place left
To find 50%, divide by 2
