Work: Find the solution of equation 8.72/2.18 = x/2.47 .
Question type: Equation
Solution:Original question:
218 25 | ÷ | 109 50 | = | x | ÷ | 247 100 |
| Left side of the equation = | 4 |
| 4 | = | x | ÷ | 247 100 |
Transposition :
| - | 100 247 | x | = | - | 4 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 4 | = | 100 247 | 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 :
100 247 | x | = | 4 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4 | ÷ | 100 247 |
| = | 4 | × | 247 100 |
| = | 1 | × | 247 25 |
We obtained :
| x | = | 247 25 |
Convert the result to decimal form :
| x | = | 9.88 |
