[ 1/1 Equation]
Work: Find the solution of equation x×66.47％ = 688 .
Question type: Equation
Solution:Original question:
| x | × | 6647 10000 | = | 688 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 688 | ÷ | 6647 10000 |
| = | 688 | × | 10000 6647 |
We obtained :
| x | = | 6880000 6647 |
Convert the result to decimal form :
| x | = | 1035.053408 |
