The problem is: X/2 - 2x + 2y/ 4y

It says to express as a single fraction in the simplest form. Do I need to find a common denominator like a regular fraction without X's or y's?

First of all - you have written a function with 3 variables, namely, X (caps), x and y. I am assuming here you meant 'x' and 'X' are same. You need write those consistently.

Second, as written, the expression you wrote is equivalent to:

\(\displaystyle \frac{X}{2} - 2x + \frac{2y}{4y}\)

I have a suspicion that is not correct!

Please re-write your expression using brackets (grouping symbols) so that we can see your problems correctly.

In addition, please show us what you have tried - so that we know where to begin to help you.

Before finding a common denominator you should try to reduce. Since variables are place holders for numbers then yes, you do have to get common denominators (after you reduce).

Now please show us your work so we can help you if you have any trouble. Thanks
