That deserves to be enshrined somewhere on the net. Anyway, the original question occured to me just before I had to go to work, as have many of my earth-shattering ideas, and I popped it off to math-fun in a hurry. Otherwise I would have forgotten all about it. I suppose if I had taken the time, I would have found 5/2 = 2.5. So, are there any of these fractions on (0, 1)? ----- Original Message ----- From: "Christian Boyer" <cboyer@club-internet.fr> To: "'math-fun'" <math-fun@mailman.xmission.com> Sent: Thursday, September 21, 2006 6:00 AM Subject: RE: [math-fun] Decimal question Not a "reduced" fractional representation, but do you like this one?
