This video tutorial covers how to multiply fractions using models and without them. It begins with an introduction to the concept of multiplying fractions, explaining the use of models to visualize the process. The tutorial then demonstrates how to simplify the results of fraction multiplication. It also presents strategies for multiplying fractions without models, including simplifying before multiplying to make calculations easier. The video emphasizes understanding the multiplication symbol as 'of' and finding the greatest common factor for simplification.
