Is 202002000200002000002000000... a rational number

Answer 1

Ok, if the number ends there at the zeros right before the ellipses, then yes that would be a rational number. The whole point of a rational number is that it ends. All whole numbers are rational numbers. It's when you get into the decimals that you have Irrational Numbers. 1/3 for instance is not a rational number. In decimals it is something like 0.3333333...etc. and never ends. The number listed up there has no decimal, meaning it has to end somewhere.
