Fraction Operations and Simplification

In this video, the teacher explains how to add, subtract, multiply, and divide fractions. The video is structured with examples for each operation, demonstrating the process of finding the least common denominator for addition and subtraction, and using multiplication and division techniques for fractions. The teacher also provides practice problems for students to solve on their own.
