Point-9 Repeating and 1

Well, this is one way to use the retired number 8 on a race-car, but only if you believe that point-9 repeating is exactly equal to one, making 7.9 (where the 9 repeats) exactly equal to 8.

I just finished putting up a video clip about this on my tutorial site (Meyer Math), but then I came across a great page that spells it out using even more proofs than I did and also includes a section of arguments and responses.
