I am fairly certain that most screen readers are likely to read the dash as a dash. On the other hand, when using mathematical expressions with fractions or more complex, you should look at using MathML, though I believe there are issues in some AT when a MATHMl expression is used as a label for a radio button and/or checkbox.
