Work: Find the solution of equation 7x/15 = 44.8% .
Question type: Equation
Solution:Original question:
| 7 | x | ÷ | 15 | = | 224 500 |
| Left side of the equation = | 7 15 | x |
7 15 | x | = | 224 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 224 500 | ÷ | 7 15 |
| = | 224 500 | × | 15 7 |
| = | 32 100 | × | 3 |
We obtained :
| x | = | 96 100 |
By reducing fraction, we can get:
| x | = | 24 25 |
Convert the result to decimal form :
| x | = | 0.96 |
