Multiplying and Simplifying Fractions

The video tutorial explains the concept of canceling fractions and generalizes it to algebraic expressions. It covers the multiplication of fractions, demonstrating how to multiply numerators and denominators. The tutorial then simplifies an algebraic expression by canceling terms and derives the final answer. Practice problems are introduced, and solutions are provided with an explanation of the marking scheme.
