Adding and Simplifying Fractions

This video tutorial explains how to add fractions with both like and unlike denominators. It covers the process of finding the least common denominator (LCD) for fractions with different denominators and demonstrates how to create equivalent fractions. The tutorial also highlights common mistakes made when adding fractions and provides several examples to illustrate the correct methods. By the end of the video, viewers will understand the importance of having a common denominator and how to simplify the resulting fractions.
