Greetings everyone! I have a quick question that involves numbers and operations. Can all repeating numbers be classified as a rational number or not?

Answer 1

If by repeating numbers you mean numbers that have a repeating sequence of decimals, the answer is yes, they can all be represented by a fraction, thus they are rationals.
e.g. 0.67321321321.... = 11209/16650

e.g. 3.181818... = 3 + 18/99 = 3 + 2/11 = 35/11
