| Question 5595:  Is  0.53 (with a repeating bar over the top of it) a rational or irrational number?
 I'm pretty sure that it's a rational number.
 Thanks!

You can put this solution on YOUR website! It's a rational number. A rational number can repeat a pattern endlessly. Actually, the real definition of a rational number is that it can be expressed as a/b where a and b have to be both integers (aka, no decimal places). In this case, 0.53 (53 repeating) is 53/99. We were able to express that in the form a/b. a=53, b=59, who are both integers.
