Work: Find the solution of equation 25200/x = 15200/109 .
Question type: Equation
Solution:Original question:
| 25200 | ÷ | x | = | 15200 | ÷ | 109 |
| Multiply both sides of the equation by: | x |
| 25200 | = | 15200 | ÷ | 109 | × | x |
Transposition :
| - | 15200 | ÷ | 109 | × | x | = | - | 25200 |
Calculate the items on the left of the equation:
| - | 15200 109 | x | = | - | 25200 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 25200 | = | 15200 109 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
15200 109 | x | = | 25200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 25200 | ÷ | 15200 109 |
| = | 25200 | × | 109 15200 |
| = | 63 | × | 109 38 |
We obtained :
| x | = | 6867 38 |
Convert the result to decimal form :
| x | = | 180.710526 |
