Work: Find the solution of equation X×0.87×0.95×0.75×0.96 = 7.2 .
Question type: Equation
Solution:Original question:
| X | × | 87 100 | × | 19 20 | × | 3 4 | × | 24 25 | = | 36 5 |
| Left side of the equation = | X | × | 14877 25000 |
14877 25000 | X | = | 36 5 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 36 5 | ÷ | 14877 25000 |
| = | 36 5 | × | 25000 14877 |
| = | 4 | × | 5000 1653 |
We obtained :
| X | = | 20000 1653 |
Convert the result to decimal form :
| X | = | 12.099214 |
