[ 1/1 Equation]
Work: Find the solution of equation H×30% = 9 .
Question type: Equation
Solution:Original question:
| H | × | 30 100 | = | 9 |
The coefficient of the unknown number is reduced to 1 :
| H | = | 9 | ÷ | 30 100 |
| = | 9 | × | 100 30 |
| = | 3 | × | 100 10 |
We obtained :
| H | = | 300 10 |
By reducing fraction, we can get:
| H | = | 30 |
