Question: Let $m,n\in\mathbb{N}$, prove that if $n|m$, $F_n|F_m$.
I've tried to use induction, but I don't really know where to start since there's $2$ numbers: $n$ and $m\ \dots$ I did induction before with just $1$ number, like proving $1+2+\cdots+n=\frac{n(n+1)}{2}$, that's only dealing with one number $n$, but with this I have no clue how to do it.
Can anyone give me a little hint on how to start, I don't want you to do whole problem for me but can I have some hint so I know where to start?
Thanks for the help!
