Adding Fractions with Different Denominators

The video tutorial explains how to add fractions with different denominators by finding a common denominator. It provides three examples: adding 2/3 and 2/9, 4/7 and 1/3, and 18 and 26. Each example demonstrates finding the lowest common multiple of the denominators, adjusting the numerators accordingly, and then adding the fractions. The tutorial concludes with an interactive exercise where viewers are asked to identify mistakes in fraction addition.
