[math-fun] Fractions test

Simplify the following fractions using nonstandard mathematics: 13/325, 143/242, 154/253, 26/65, 176/275, 187/286, 19/95, 124/217, 148/185, 187/748 I remember seeing fractions of this sort in a book privately published by Paul Yearout, and I know I've seen them elsewhere. Is there a definitive paper on these sorts of fractions? I didn't find a nice one where just 1's or 2's got eliminated. --Ed Pegg Jr.
