Work: Find the solution of equation x*99.975%-123.752*100.025% = 1/10 .
Question type: Equation
Solution:Original question:
| x | × | 3999 4000 | − | 15469 125 | × | 4001 4000 | = | 1 | ÷ | 10 |
| Left side of the equation = | x | × | 3999 4000 | − | 61891469 500000 |
3999 4000 | x | − | 61891469 500000 | = | 1 | ÷ | 10 |
| Right side of the equation = | 1 10 |
3999 4000 | x | − | 61891469 500000 | = | 1 10 |
Transposition :
3999 4000 | x | = | 1 10 | + | 61891469 500000 |
Combine the items on the right of the equation:
3999 4000 | x | = | 61941469 500000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 61941469 500000 | ÷ | 3999 4000 |
| = | 61941469 500000 | × | 4000 3999 |
| = | 61941469 125 | × | 1 3999 |
We obtained :
| x | = | 61941469 499875 |
Convert the result to decimal form :
| x | = | 123.913916 |
