I know allocF must be class method because it returns [Fraction alloc].
But count can be a instance method, right?

The count: method, needs to be a class method, or it would not work correctly.

What it is doing is generating a counter which will be added to, each time an instance of the Fraction class is created.

Therefore, if it was an instance method, then the result would only be 1 each time.
