Consider the rational number which in decimal form is .12345345345345...
It begins with two non-repeating digits followed by a block of 3 digits which repeats.
For the generalized repeating decimal
Where [a] has n digits and [b] has m digits.
Find a general way to transform it into a rational number of the form p/r.
(In reply to A little mistake
by Chesca Ciprian)
True. My original intention was to write the above expression in conformity with the other comments.
However, a typographical anomaly on my part, in writing n instead of 10^n, dictated otherwise.
Accordingly, I confirm having corrected the foregoing lacuna in my original post.
