[ 1/1 Equation]
Work: Find the solution of equation x*0.79*3.79*1.05 = 2.82 .
Question type: Equation
Solution:Original question:
| x | × | 79 100 | × | 379 100 | × | 21 20 | = | 141 50 |
| Left side of the equation = | x | × | 628761 200000 |
628761 200000 | x | = | 141 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 141 50 | ÷ | 628761 200000 |
| = | 141 50 | × | 200000 628761 |
| = | 47 | × | 4000 209587 |
We obtained :
| x | = | 188000 209587 |
Convert the result to decimal form :
| x | = | 0.897002 |
