| ( | R | × | 1 2 | × | 2 | × | 60 100 | ) | ÷ | ( | 1 | − | R | × | 1 2 | × | 2 | × | 60 100 | ) | = | 10 100 |
| Multiply both sides of the equation by: | ( | 1 | − | R | × | 1 2 | × | 2 | × | 60 100 | ) |
| ( | R | × | 1 2 | × | 2 | × | 60 100 | ) | = | 10 100 | ( | 1 | − | R | × | 1 2 | × | 2 | × | 60 100 | ) |
| R | × | 1 2 | × | 2 | × | 60 100 | = | 10 100 | ( | 1 | − | R | × | 1 2 | × | 2 | × | 60 100 | ) |
| R | × | 1 2 | × | 2 | × | 60 100 | = | 10 100 | × | 1 | − | 10 100 | R | × | 1 2 | × | 2 | × | 60 100 |
| R | × | 3 5 | = | 1 10 | − | 3 50 | R |
3 5 | R | + | 3 50 | R | = | 1 10 |
33 50 | R | = | 1 10 |
| R | = | 1 10 | ÷ | 33 50 |
