93293 100 | = | 1000 | ÷ | ( | 1 | + | r | × | 1 | ) |
| Multiply both sides of the equation by: | ( | 1 | + | r | × | 1 | ) |
93293 100 | ( | 1 | + | r | × | 1 | ) | = | 1000 |
93293 100 | × | 1 | + | 93293 100 | r | × | 1 | = | 1000 |
93293 100 | + | 93293 100 | r | = | 1000 |
93293 100 | r | = | 1000 | − | 93293 100 |
93293 100 | r | = | 6707 100 |
| r | = | 6707 100 | ÷ | 93293 100 |
| = | 6707 100 | × | 100 93293 |
| = | 6707 | × | 1 93293 |
| r | = | 6707 93293 |
| r | = | 0.071892 |
