Extracting a Bernoulli Number

Suppose that the power series of $f(x) = \dfrac{x}{e^x-1}$ is $\displaystyle\sum_{n=0}^{\infty}\frac{B_n}{n!}x^n$. Determine the value of $B_{10}$. The answer is in the form $\frac{\alpha}{\beta}$ for coprime integers $\alpha$ and $\beta$. Input the answer as the sum $\alpha +\beta$.
