Work: Find the solution of equation 0.131/x = 0.1289/0.86289 .
Question type: Equation
Solution:Original question:
131 1000 | ÷ | x | = | 1289 10000 | ÷ | 86289 100000 |
| Multiply both sides of the equation by: | x |
131 1000 | = | 1289 10000 | ÷ | 86289 100000 | × | x |
Transposition :
| - | 1289 10000 | ÷ | 86289 100000 | × | x | = | - | 131 1000 |
Calculate the items on the left of the equation:
| - | 12890 86289 | x | = | - | 131 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
131 1000 | = | 12890 86289 | 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 :
12890 86289 | x | = | 131 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 131 1000 | ÷ | 12890 86289 |
| = | 131 1000 | × | 86289 12890 |
We obtained :
| x | = | 11303859 12890000 |
Convert the result to decimal form :
| x | = | 0.876948 |
