Work: Find the solution of equation 0.3 = 0.5/（19.99*x) .
Question type: Equation
Solution:Original question:
3 10 | = | 1 2 | ÷ | ( | 1999 100 | x | ) |
| Multiply both sides of the equation by: | ( | 1999 100 | x | ) |
3 10 | ( | 1999 100 | x | ) | = | 1 2 |
3 10 | × | 1999 100 | x | = | 1 2 |
5997 1000 | x | = | 1 2 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1 2 | ÷ | 5997 1000 |
| = | 1 2 | × | 1000 5997 |
| = | 1 | × | 500 5997 |
We obtained :
| x | = | 500 5997 |
Convert the result to decimal form :
| x | = | 0.083375 |
