Is 0.99 Periodical Equal to 1?
Date: 25 Apr 1995 06:26:53 -0400 From: Karsten Koops Subject: 0,999. = 1 ? Hello there! Today I had a discussion with my collegues about whether 0,99. periodically is the same value as 1. My statement is: Suppose X = 0,99. periodical Multiply by 10, so you get 10X=9,99. Subtract 1X (0,99.) 9X=9 Divide by 9 and you get X=1 Is this equation and therefore the above statement correct? By the way, could you tell me, who is/are DR.MATH and SWARTHMORE? Thanks much, bye KOOPS@MAGNET.AT --- OffRoad 0.99o unregistered

Another way to show it is that if 1 and 0,9999... were two different numbers, you'd be able to find numbers in between them, but you can't. The Dr.s of math are undergraduate students at Swarthmore College. Swarthmore is a 4-year liberal arts college just south of Philadelphia, PA. -K
