Using the Least Common Denominator

The video tutorial explains how to clear fractions from equations by identifying the least common denominator (LCD) and multiplying each term by it. This process simplifies the equation, making it easier to solve. The tutorial includes an example problem to demonstrate the steps, emphasizing the importance of using the multiplication property to eliminate denominators. The instructor also provides tips on identifying the LCD and encourages viewers to subscribe to the channel.
