We're hoping that nobody ever taught you that every fraction has a "whole number" connected to it somehow. It doesn't. Let's put it as simply as we can: If you have one half of a pizza, then how many whole pizzas is that ? And if you have one half of a dollar, then how many whole dollars is that ? One half is just what it says . . . one half. There is no whole number for it. You'd need to get another half from somewhere and put them together just to make the smallest whole number there is.

Two and a half would be called a mixed number, because it has a whole number and a fraction.
