:::::::::"I cannot continue this discussion with you because you are mentally inferior to me." Nothing could be further from the truth.  Gustave is right, every number with a repeating decimal is a rational number.  There are no numbers with repeating decimals that are irrational.  Look up the wikipedia page for repeating decimals if you think we're wrong.  Don't say you're smarter than the other posters, that only tells them that you aren't.
