☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation x*3.99*2.99 = 4.13 .
Question type: Equation
Solution:Original question:
| x | × | 399 100 | × | 299 100 | = | 413 100 |
| Left side of the equation = | x | × | 119301 10000 |
119301 10000 | x | = | 413 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 413 100 | ÷ | 119301 10000 |
| = | 413 100 | × | 10000 119301 |
| = | 59 | × | 100 17043 |
We obtained :
| x | = | 5900 17043 |
Convert the result to decimal form :
| x | = | 0.346183 |
