Work: Find the solution of equation （400+X）/32.07 = 14.47 .
Question type: Equation
Solution:Original question:
| ( | 400 | + | X | ) | ÷ | 3207 100 | = | 1447 100 |
| Left side of the equation = | 400 | × | 100 3207 | + | X | × | 100 3207 |
| = | 40000 3207 | + | X | × | 100 3207 |
40000 3207 | + | 100 3207 | X | = | 1447 100 |
Transposition :
100 3207 | X | = | 1447 100 | − | 40000 3207 |
Combine the items on the right of the equation:
100 3207 | X | = | 640529 320700 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 640529 320700 | ÷ | 100 3207 |
| = | 640529 320700 | × | 3207 100 |
| = | 640529 106900 | × | 1069 100 |
We obtained :
| X | = | 684725501 10690000 |
By reducing fraction, we can get:
| X | = | 640529 10000 |
Convert the result to decimal form :
| X | = | 64.0529 |
