Work: Find the solution of equation x*1.28*1.4*1.31 = 0.38 .
Question type: Equation
Solution:Original question:
| x | × | 32 25 | × | 7 5 | × | 131 100 | = | 19 50 |
| Left side of the equation = | x | × | 7336 3125 |
7336 3125 | x | = | 19 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 19 50 | ÷ | 7336 3125 |
| = | 19 50 | × | 3125 7336 |
| = | 19 2 | × | 125 7336 |
We obtained :
| x | = | 2375 14672 |
Convert the result to decimal form :
| x | = | 0.161873 |
