1/m - 1/n
m = 2/5 n = 3/4
The correct answer is 1 1/6
But I would like to know how to solve it.

What is the answer?[/QUOTE]
Hello,
$\displaystyle \frac{1}{m}-\frac{1}{n}$. Plug in the values you know:
$\displaystyle \frac{1}{\frac{2}{5}}-\frac{1}{\frac{3}{4}}$ =
$\displaystyle \frac{5}{2}-\frac{4}{3}=\frac{3 \cdot 5-2 \cdot 4}{6}=\frac{7}{6}$
