Question 9823
not sure what you mean "by Series". The only way i am aware is to do the following:


look at the repeating part, which here is 123. We need one whole section in front of the decimal point, so we need to multiply by 1000...


let    r =   0.123123123...
so 1000r = 123.123123123...


now subtract the first from the second, leaving 999r = 123


so r = 123/999
