| i | = | ( | 115 2 | ÷ | ( | 4157 500 | × | 310 | ) | ) |
| i | = | 115 2 | ÷ | ( | 4157 500 | × | 310 | ) |
| Multiply both sides of the equation by: | ( | 4157 500 | × | 310 | ) |
| i | ( | 4157 500 | × | 310 | ) | = | 115 2 |
| i | × | 4157 500 | × | 310 | = | 115 2 |
| i | × | 128867 50 | = | 115 2 |
| i | = | 115 2 | ÷ | 128867 50 |
| = | 115 2 | × | 50 128867 |
| = | 115 | × | 25 128867 |
| i | = | 2875 128867 |
| i | = | 0.02231 |
