You don't happen to mean 0.64666666666666666666..., do you? If you do, then that is really nasty notation. If someone showed you how to write that, please be more careful about listening to that individual's advice in mathematics. :cry: If you invvented it yourself, you are not hte first, but it remains quite inappropriate.

There is a standard trick for that.

S = 0.64666666666666666666...
100*S = 64.666666666666666...
100*S = 64 + 2/3 = 64*(3/3) + 2/3 = (192+2)/3 = 194/3
100*S = 194/3
S = 194/300 = 97/150

Check 97/150 = 0.64666666666666... - Check!
 
Got answer
