Commen Sense wise, yeah your right...

BUt this is math, and really, commen sense isn't going to work

Mathmatically, if there is no known number between 2 numbers...The numbers must be equal

Sure, you know that 0.8r and 1 aren't the same, despite 0.8r being a repeat...Because you DO know numbers between those 2...Despite one being rational and one being irrational
