Percent means out of 100
| Percentage | Fraction | Decimal |
|---|---|---|
| 50% | ½ | 0,5 |
| 25% | ¼ | 0,25 |
| 75% | ¾ | 0,75 |
| 10% | ¹⁄₁₀ | 0,1 |
| 100% | 1 whole | 1 |
- A percentage of an amount: 20% of 150 = ²⁰⁄₁₀₀ × 150 = 30.
- Shortcut: 10% = divide by 10; 5% = half of that.
- A mark as a percentage: 18 out of 20 = ¹⁸⁄₂₀ × 100 = 90%.
Remember this and test yourself
- % means out of 100.
- 50% = ½; 25% = ¼; 10% = ¹⁄₁₀.
- 20% of 150 = 30.
- Mark → %: divide, then multiply by 100.
