Adding Fractions and LCM

This video tutorial explains how to add fractions using the Least Common Multiple (LCM) method. It covers two types of fraction addition: one with common factors in the denominators and another without. The tutorial provides step-by-step solutions for each type, demonstrating how to find the LCM, perform the necessary calculations, and simplify the results. The video emphasizes the importance of understanding the LCM method, which is also applicable in algebra.
