The answer is 25/176, unless you mean 5/(8n-4), in which case it is 33/16

That depends what you mean, either:

$$\frac{2}{5}=\frac{5}{8n-4}$$

$$2(8n-4) = 25$$

Or:

$$\frac{2}{5}=\frac{5}{8n} - 4$$

$$2 = \frac{25}{8n} - 20$$

$$22 = \frac{25}{8n}$$

$$176n=25$$

I just thought you might also mean:

$$\frac{2}{5}=\frac{5}{8}n-4$$

$$\frac{16}{5}=5n-32$$

$$\frac{176}{5}=5n$$
