[ 1/1 Equation]
Work: Find the solution of equation 219.9×11.9 = 1.2x .
Question type: Equation
Solution:Original question:
2199 10 | × | 119 10 | = | 6 5 | x |
| Left side of the equation = | 261681 100 |
261681 100 | = | 6 5 | x |
Transposition :
| - | 6 5 | x | = | - | 261681 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
261681 100 | = | 6 5 | 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 :
6 5 | x | = | 261681 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 261681 100 | ÷ | 6 5 |
| = | 261681 100 | × | 5 6 |
| = | 87227 20 | × | 1 2 |
We obtained :
| x | = | 87227 40 |
Convert the result to decimal form :
| x | = | 2180.675 |
