Work: Find the solution of equation f = 2.5*1.195/(2*(1.195-1)) .
Question type: Equation
Solution:Original question:
| f | = | 5 2 | × | 239 200 | ÷ | ( | 2 | ( | 239 200 | − | 1 | ) | ) |
| Multiply both sides of the equation by: | ( | 2 | ( | 239 200 | − | 1 | ) | ) |
| f | ( | 2 | ( | 239 200 | − | 1 | ) | ) | = | 5 2 | × | 239 200 |
| f | × | 2 | ( | 239 200 | − | 1 | ) | = | 5 2 | × | 239 200 |
| f | × | 2 | ( | 239 200 | − | 1 | ) | = | 239 80 |
| f | × | 2 | × | 239 200 | − | f | × | 2 | × | 1 | = | 239 80 |
| f | × | 239 100 | − | f | × | 2 | = | 239 80 |
39 100 | f | = | 239 80 |
The coefficient of the unknown number is reduced to 1 :
| f | = | 239 80 | ÷ | 39 100 |
| = | 239 80 | × | 100 39 |
| = | 239 4 | × | 5 39 |
We obtained :
| f | = | 1195 156 |
Convert the result to decimal form :
| f | = | 7.660256 |
