"Parts of a whole" refers to how individual components contribute to a complete entity. For example, a pizza consists of various parts like the crust, sauce, cheese, and toppings. Each ingredient plays a role in creating the overall flavor and texture, illustrating how smaller elements combine to form a larger item. In mathematics, the concept is often represented as fractions. A whole can be divided into equal parts, such as dividing a cake into slices. Each slice represents a fraction of the entire cake, demonstrating how parts relate to the whole in both tangible and abstract contexts.
