Recall that

$e^x = 1 + \frac{x}{1!} + \frac{x^2}{2!} + \frac{x^3}{3!} + \cdots.$
Then what is the value of
$\large \frac{\frac{2}{3!} + \frac{4}{5!} + \frac{6}{7!} + \cdots}{\frac{2}{1!} + \frac{4}{3!} + \frac{6}{5!} + \cdots}\, ?$

$$

**Notation:** $!$ is the factorial notation. For example, $8! = 1\times2\times3\times\cdots\times8$.
