| 1% | Move the decimal two places left. 1% of 2,400 = 24 |
| 5% | Half of 10%. 5% of 1,500 = 150 ÷ 2 = 75 |
| 2% | 1% doubled. 2% of 2,400 = 24 × 2 = 48 |
| 20% | 10% doubled. 20% of 450 = 45 × 2 = 90 |
| 25% | Divide by 4. 25% of 1,120 = 1,120 ÷ 4 = 280 |
| 50% | Half. 50% of 3,400 = 1,700 |
| 15% | 10% + 5%. 15% of 800 = 80 + 40 = 120 |
| 75% | Three quarters. 75% of 120 = 30 × 3 = 90 |
