Writing Wholes as Fractions

The video tutorial explains the concept of unit fractions, using an area model and a number line to illustrate how fractions like 1/4 are represented. It demonstrates how combining unit fractions can form larger fractions, such as 3/4, and explains that when all parts of a model are combined, the fraction equals a whole, like 4/4 equaling 1. The lesson concludes with the general rule that a fraction with the same numerator and denominator represents a whole.
