Work: Find the solution of equation 688÷x = 66.47 .
Question type: Equation
Solution:Original question:
| 688 | ÷ | x | = | 6647 100 |
| Multiply both sides of the equation by: | x |
| 688 | = | 6647 100 | x |
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 :
6647 100 | x | = | 688 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 688 | ÷ | 6647 100 |
| = | 688 | × | 100 6647 |
We obtained :
| x | = | 68800 6647 |
Convert the result to decimal form :
| x | = | 10.350534 |
