Understanding Fractions

The video tutorial introduces fractions using a pizza example, explaining how fractions represent parts of a whole. It details the two parts of a fraction: the numerator and the denominator. Visual aids like circles and rectangles are used to illustrate fractions, and real-life examples, such as pets, demonstrate their application. The video concludes with a summary of the key concepts.
