The video tutorial explains how to simplify complex fractions using the LCD method. It begins with identifying the least common denominator (LCD) for the fractions involved, then demonstrates multiplying both the numerator and the denominator by the LCD. The process involves using the distributive property and simplifying the resulting expressions. The tutorial concludes with reducing the expression to its lowest terms, highlighting the importance of careful calculation and simplification.
