(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex] \frac{(kn)!}{(kn+k)!} [/tex]

I was thinking:

(kn)! = 1*2*3......(kn)

(kn+k)! = 1*2*3......(kn)(kn+k)

and I would be left with 1/kn+k

But my book has the answer as:

[tex] \frac{1}{(kn+k)(kn+k-1)....(kn+1)} [/tex]

How can I arrive to that?
