| 90 | = | X | × | 1 10 | ( | 17 5 | × | 1 1000000 | × | 50000 | × | 16 | ) |
| Right side of the equation = | X | × | 1 10 | × | 17 5 | × | 1 1000000 | × | 50000 | × | 16 |
| = | X | × | 34 125 |
| 90 | = | 34 125 | X |
| - | 34 125 | X | = | - | 90 |
| 90 | = | 34 125 | X |
34 125 | X | = | 90 |
| X | = | 90 | ÷ | 34 125 |
| = | 90 | × | 125 34 |
| = | 45 | × | 125 17 |
| X | = | 5625 17 |
| X | = | 330.882353 |
