# 5/m - 1/2

#### duBxStep

Is it just 5/m - 1/2 because it cant be simplified any further?

You have to clarify what you are asking. Using parentheses would really help.

Do you mean you want to do $$\displaystyle \frac{5}{m} - \frac{1}{2}$$?

In which case, you can take the least common denominator which is $$\displaystyle 2m$$ and proceed like you are doing ordinary fractions.

This confuses me because if 2m is the l.c.d. then wouldn't it be something like....

10/2m - 1m/2m?

Or is it...

10/2m - 1/2m?

Or is it...

10/2m - 1/2? But m isnt on both sides here?

Actually, to answer your original question, there isn't anything more we can do to $$\displaystyle \frac{5}{m} - \frac{1}{2}$$ to simplify it. We can only do the operation, which is subtraction. If you use 2m as the least common denominator, you'll get $$\displaystyle \frac{5}{m} - \frac{1}{2} = \frac{{10 - m}}{{2m}}$$. And that's pretty much it. (Nod)
