Dividing Mixed Numbers and Fractions

This video tutorial teaches how to divide fractions and mixed numbers using models. It covers three examples: dividing two and a half by one-half, one and three-fourths by one-half, and two and one-sixth by two-thirds. The instructor uses visual models to demonstrate how many fractional groups can be formed from the given numbers, emphasizing the concept of dividing fractions through practical examples.
