h:then 10x=599.99999....
- 1x -59.9999...
---------------------
9x = 540
x = 59.99999... = 60

If you assume that .99 repeating is actually 1. Then the same logic means that .88 repeating is really .99 repeating. Then .77 repeating is really .88 repeating. Also .66 repeating is .77 repeating. So you are saying that .66 repeating is really 1?
And they assumed that the world was flat, it wasn't "blatently obvious".
It doesn't take some fancy formula to show that 1 is different than 2. Nor .999 repeating is different than any other number, including 1.

0.8repeating = 0.8 + 0.08 +0.008 + ... = sum(0 to inf) 0.8*1/10^n = 0.8/(1-1/10) = 8/9
Same argument as before.
