Dividing Mixed Numbers and Fractions

In this video, Mr. J explains how to divide mixed numbers and whole numbers through two examples. The first example demonstrates dividing a mixed number by a whole number, while the second example covers dividing a whole number by a mixed number. Key steps include converting numbers to improper fractions, using the 'keep, switch, flip' method, and simplifying results. The video emphasizes the importance of cancellation to simplify calculations and provides a comparison of results with and without cancellation.

What is the first step in dividing mixed numbers and whole numbers?

• Subtract the smaller from the larger

• Convert them to improper fractions

• Add them together

• Multiply them directly

In the first example, what is the improper fraction equivalent of 8 and 2/3?

• 20/3

• 22/3

• 24/3

• 26/3
