Deciding to multiply a proportion by the LCD rather than using cross multiplication

The video tutorial demonstrates how to solve a proportion using the Least Common Denominator (LCD) method. The instructor explains the process of multiplying both sides of the equation by the LCD to simplify the problem, avoiding the need for cross multiplication. The solution is then simplified by identifying the greatest common divisor, resulting in the final answer. The tutorial emphasizes the efficiency of using the LCD method for solving proportions.
