Dividing Whole Numbers by Fractions with Models

In this video, Mr. J explains how to model dividing whole numbers by fractions using two examples. The first example demonstrates dividing 5 by 3/4, resulting in 6 and 2/3. The second example shows dividing 2 by 2/5, resulting in 5. The video emphasizes using shapes to represent whole numbers and dividing them into fractional parts. Mr. J also provides links to additional resources for further learning.
