[ 1/1 Equation]
Work: Find the solution of equation (（2263.7-X）/2263.7)*100 = 0.2 .
Question type: Equation
Solution:Original question:
| ( | ( | 22637 10 | − | X | ) | ÷ | 22637 10 | ) | × | 100 | = | 1 5 |
| Left side of the equation = | ( | 22637 10 | − | X | ) | ÷ | 22637 10 | × | 100 |
| = | ( | 22637 10 | − | X | ) | × | 1000 22637 |
| = | 22637 10 | × | 1000 22637 | − | X | × | 1000 22637 |
| = | 2263700 22637 | − | X | × | 1000 22637 |
2263700 22637 | − | 1000 22637 | X | = | 1 5 |
Transposition :
| - | 1000 22637 | X | = | 1 5 | − | 2263700 22637 |
Combine the items on the right of the equation:
| - | 1000 22637 | X | = | - | 11295863 113185 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
11295863 113185 | = | 1000 22637 | 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 :
1000 22637 | X | = | 11295863 113185 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 11295863 113185 | ÷ | 1000 22637 |
| = | 11295863 113185 | × | 22637 1000 |
We obtained :
| X | = | 255704450731 113185000 |
