Simplifying exponential fraction

I have this exponential fraction

$$\frac{{2}^{n+1}}{{5}^{n-1}}$$

I was wondering how we simplify something like this.

I know if the top and bottom had the same like $\frac{{2}^{n+1}}{{2}^{n+1}}$, you would just subtract the exponent.

But in my situation, I'm not too sure how to tackle it.
