Work: Find the solution of equation 20.3×25.4÷x = 20.3×15.2÷120 .
Question type: Equation
Solution:Original question:
203 10 | × | 127 5 | ÷ | x | = | 203 10 | × | 76 5 | ÷ | 120 |
| Multiply both sides of the equation by: | x |
203 10 | × | 127 5 | = | 203 10 | × | 76 5 | ÷ | 120 | × | 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 :
203 10 | × | 76 5 | ÷ | 120 | × | x | = | 203 10 | × | 127 5 |
Calculate the items on the left of the equation:
3857 1500 | x | = | 203 10 | × | 127 5 |
Calculate the items on the right of the equation:
3857 1500 | x | = | 25781 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 25781 50 | ÷ | 3857 1500 |
| = | 25781 50 | × | 1500 3857 |
| = | 3683 | × | 30 551 |
We obtained :
| x | = | 110490 551 |
By reducing fraction, we can get:
| x | = | 3810 19 |
Convert the result to decimal form :
| x | = | 200.526316 |
