Work: Find the solution of equation x*3.99*1.15 = 4.03 .
Question type: Equation
Solution:Original question:
| x | × | 399 100 | × | 23 20 | = | 403 100 |
| Left side of the equation = | x | × | 9177 2000 |
9177 2000 | x | = | 403 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 403 100 | ÷ | 9177 2000 |
| = | 403 100 | × | 2000 9177 |
| = | 403 | × | 20 9177 |
We obtained :
| x | = | 8060 9177 |
Convert the result to decimal form :
| x | = | 0.878283 |
