Multiplying Fractions and Models

This video tutorial teaches how to multiply fractions by multiplying across numerators and denominators. It begins with a model-based approach, demonstrating how to find half of two-thirds using a rectangle model. The tutorial then explains how to multiply fractions without models by directly multiplying numerators and denominators. An example problem involving a garden is used to illustrate the concept further. The lesson concludes by emphasizing the simplicity of multiplying fractions compared to adding or subtracting them.
