[ 1/1 Equation]
Work: Find the solution of equation x*1.03*1.3*(1+100%) = 2.34 .
Question type: Equation
Solution:Original question:
| x | × | 103 100 | × | 13 10 | ( | 1 | + | 100 100 | ) | = | 117 50 |
| Left side of the equation = | x | × | 1339 1000 | ( | 1 | + | 100 100 | ) |
| x | × | 1339 1000 | ( | 1 | + | 100 100 | ) | = | 117 50 |
| Left side of the equation = | x | × | 1339 1000 | × | 1 | + | x | × | 1339 1000 | × | 100 100 |
| = | x | × | 1339 1000 | + | x | × | 1339 1000 |
| = | 1339 500 | x |
1339 500 | x | = | 117 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 117 50 | ÷ | 1339 500 |
| = | 117 50 | × | 500 1339 |
| = | 117 | × | 10 1339 |
We obtained :
| x | = | 1170 1339 |
By reducing fraction, we can get:
| x | = | 90 103 |
Convert the result to decimal form :
| x | = | 0.873786 |
