The video tutorial explains how to divide whole numbers by fractions using visual models. It starts with dividing by unit fractions, demonstrating how many groups of a fraction fit into a whole number. The tutorial then progresses to dividing by non-unit fractions, using a bicycle race scenario to illustrate the concept. Finally, a pizza problem is used to show how to divide whole numbers by fractions with numerators greater than one. The lesson emphasizes using models to visualize and solve these division problems.

What is a unit fraction?

• A fraction with a numerator greater than one

• A fraction with a numerator of one
