Hello, So, me and my brother were talking about math, and he asked me a question that I want some help on. Here is what he said: "Take any number x where x equals a non repeating decimal rational number. If x/y=a, and y equals a non repeating decimal rational number, then does there exist a number x such that a does NOT equal a non repeating decimal rational number?" I am stumped, to be completely honest. Maybe I am trying too hard. Could someone help me figure this out? Jared

If x = 0.2 and y = 0.6, a = 0.33333333... (This seems too easy  maybe more is required.)

It doesn't really come from anywhere. He just made it up. It does seem too easy, maybe more is required that I don't know. I'll ask him.
