1 100 | = | B | ÷ | ( | 1 | − | B | ) |
| Multiply both sides of the equation by: | ( | 1 | − | B | ) |
1 100 | ( | 1 | − | B | ) | = | B |
1 100 | × | 1 | − | 1 100 | B | = | B |
1 100 | − | 1 100 | B | = | B |
| - | 1 100 | B | − | B | = | - | 1 100 |
| - | 101 100 | B | = | - | 1 100 |
1 100 | = | 101 100 | B |
101 100 | B | = | 1 100 |
| B | = | 1 100 | ÷ | 101 100 |
| = | 1 100 | × | 100 101 |
| = | 1 | × | 1 101 |
| B | = | 1 101 |
| B | = | 0.009901 |
