@copper.hat, $r_x$ would be elements in set $R$. Sorry, that is not mentioned clearly in the question.

+1. thanks for answer. I got confused with orderable and countable. For the fact, can you explain how real numbers are orderable / uncountable? (not in comments please, in above answer)

Wonderful answer. I will wait to see other answers as well. The reason for my question is, countability of rational numbers, I am confusing the the method to show rational numbers are countable with a kind of ordering. What are we doing when we write 1, 1/2, 1/3, 1/4.... 2/1, 2/2, 2/3... ?
