Work: Find the solution of equation x*0.88*2.55 = 7.15 .
Question type: Equation
Solution:Original question:
| x | × | 22 25 | × | 51 20 | = | 143 20 |
| Left side of the equation = | x | × | 561 250 |
561 250 | x | = | 143 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 143 20 | ÷ | 561 250 |
| = | 143 20 | × | 250 561 |
| = | 13 2 | × | 25 51 |
We obtained :
| x | = | 325 102 |
Convert the result to decimal form :
| x | = | 3.186275 |
