| ( | 1 | ÷ | x | ) | − | 1 | ÷ | 33 25 | = | 1 4 | × | 87 5 |
| 1 | ÷ | x | − | 1 | ÷ | 33 25 | = | 1 4 | × | 87 5 |
| 1 | ÷ | x | − | 25 33 | = | 87 20 |
| Multiply both sides of the equation by: | x |
| 1 | − | 25 33 | x | = | 87 20 | x |
| - | 25 33 | x | − | 87 20 | x | = | - | 1 |
| - | 3371 660 | x | = | - | 1 |
| 1 | = | 3371 660 | x |
3371 660 | x | = | 1 |
| x | = | 1 | ÷ | 3371 660 |
| = | 1 | × | 660 3371 |
| x | = | 660 3371 |
| x | = | 0.195788 |
