Work: Find the solution of equation （29.73-20）/（30-29.73） = （a-1.05）/（0.8007-a） .
Question type: Equation
Solution:Original question:
| ( | 2973 100 | − | 20 | ) | ÷ | ( | 30 | − | 2973 100 | ) | = | ( | a | − | 21 20 | ) | ÷ | ( | 8007 10000 | − | a | ) |
| Multiply both sides of the equation by: | ( | 30 | − | 2973 100 | ) | , | ( | 8007 10000 | − | a | ) |
| ( | 2973 100 | − | 20 | ) | ( | 8007 10000 | − | a | ) | = | ( | a | − | 21 20 | ) | ( | 30 | − | 2973 100 | ) |
