| 1450 | ÷ | ( | 2000 | ÷ | 480 | × | 2400 | ÷ | 1000 | ) | = | X |
| Multiply both sides of the equation by: | ( | 2000 | ÷ | 480 | × | 2400 | ÷ | 1000 | ) |
| 1450 | = | X | ( | 2000 | ÷ | 480 | × | 2400 | ÷ | 1000 | ) |
| 1450 | = | X | × | 2000 | ÷ | 480 | × | 2400 | ÷ | 1000 |
| 1450 | = | X | × | 10 |
| - | 10 | X | = | - | 1450 |
| 1450 | = | 10 | X |
| 10 | X | = | 1450 |
| X | = | 1450 | ÷ | 10 |
| = | 1450 | × | 1 10 |
| = | 145 | × | 1 |
| X | = | 145 |
