Neat. But I don't think I've ever heard anything about that fraction before. :-? | |

I have. Many Integers that form the reccuring part of a fraction (a reccuring fraction by the way is any fraction that has prime factors other than 2 and 5) also have interesting proporties. :) | |

Being that I've memorized the repeating digits of fractions 1/2 to 1/20, this one was easy for me. :D |
