Work: Find the solution of equation 45.1/X = 141.2/25 .
Question type: Equation
Solution:Original question:
451 10 | ÷ | X | = | 706 5 | ÷ | 25 |
| Multiply both sides of the equation by: | X |
451 10 | = | 706 5 | ÷ | 25 | × | X |
Transposition :
| - | 706 5 | ÷ | 25 | × | X | = | - | 451 10 |
Calculate the items on the left of the equation:
| - | 706 125 | X | = | - | 451 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
451 10 | = | 706 125 | 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 :
706 125 | X | = | 451 10 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 451 10 | ÷ | 706 125 |
| = | 451 10 | × | 125 706 |
| = | 451 2 | × | 25 706 |
We obtained :
| X | = | 11275 1412 |
Convert the result to decimal form :
| X | = | 7.985127 |
