[ 1/1 Equation]
Work: Find the solution of equation x*0.86*1.72*1.99*2.99 = 4.09 .
Question type: Equation
Solution:Original question:
| x | × | 43 50 | × | 43 25 | × | 199 100 | × | 299 100 | = | 409 100 |
| Left side of the equation = | x | × | 110017349 12500000 |
110017349 12500000 | x | = | 409 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 409 100 | ÷ | 110017349 12500000 |
| = | 409 100 | × | 12500000 110017349 |
| = | 409 | × | 125000 110017349 |
We obtained :
| x | = | 51125000 110017349 |
Convert the result to decimal form :
| x | = | 0.464699 |
