Does $\frac{3n+21}{n+3} = \frac{n+7}{\frac{n}{3}+1}$?

If so, I think that means $n$ must always be divisible by 3, correct? Maybe not...?

We might also notice that $\frac{n+7}{n+3}$ must be a natural number, correct?

Do either of these things help? What have you tried so far?
Thanks from topsquark

Parentheses would also be nice. I am (reasonably) guessing that you want the form (3n + 21)/(n + 3). Details are important.
