Work: Find the solution of equation 78.85/123.85 = x/396.162 .
Question type: Equation
Solution:Original question:
1577 20 | ÷ | 2477 20 | = | x | ÷ | 198081 500 |
| Left side of the equation = | 1577 2477 |
1577 2477 | = | x | ÷ | 198081 500 |
Transposition :
| - | 500 198081 | x | = | - | 1577 2477 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1577 2477 | = | 500 198081 | 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 :
500 198081 | x | = | 1577 2477 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1577 2477 | ÷ | 500 198081 |
| = | 1577 2477 | × | 198081 500 |
We obtained :
| x | = | 312373737 1238500 |
Convert the result to decimal form :
| x | = | 252.219408 |
