I know the Arithmetic proof and everything but how to explain this practically to a kid who just started understanding the numbers?

Not sure how appropriate it would be for a 5 year old, since I’ve seen many adults who struggle with the concept, but then again it might be because of no one explaining it to them when they were 5, and them being stuck with it inertially… so here goes.
It is important to understand, that a number is _different_ from the way you write it down. 1.5, 1.5000, 1 1/2 and 3/2 are different ways of writing the same number – the same point on an axis. Once that is established, you can say – see, fundamentally, 1 and 0.(9) are two different ways of representing the same number, and after that you use one of the many proofs available for that.
