[ 1/1 Equation]
Work: Find the solution of equation 80×20%/80+x×100% = 10% .
Question type: Equation
Solution:Original question:
| 80 | × | 20 100 | ÷ | 80 | + | x | × | 100 100 | = | 10 100 |
| Left side of the equation = | 1 5 | + | x | × | 100 100 |
1 5 | + | 100 100 | x | = | 10 100 |
Transposition :
100 100 | x | = | 10 100 | − | 1 5 |
Combine the items on the right of the equation:
100 100 | x | = | - | 1 10 |
| = | - | 1 10 | × | 100 100 |
| = | - | 1 | × | 10 100 |
We obtained :
| x | = | - | 10 100 |
By reducing fraction, we can get:
| x | = | - | 1 10 |
Convert the result to decimal form :
| x | = | - 0.1 |
