[ 1/1 Equation]
Work: Find the solution of equation 0.4/100.58 = x/32.1 .
Question type: Equation
Solution:Original question:
2 5 | ÷ | 5029 50 | = | x | ÷ | 321 10 |
| Left side of the equation = | 20 5029 |
20 5029 | = | x | ÷ | 321 10 |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
10 321 | x | = | 20 5029 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 20 5029 | ÷ | 10 321 |
| = | 20 5029 | × | 321 10 |
| = | 2 5029 | × | 321 |
We obtained :
| x | = | 642 5029 |
By reducing fraction, we can get:
| x | = | 6 47 |
Convert the result to decimal form :
| x | = | 0.12766 |
