On number 6.25, on which it tells you to find the lcm of two variables m and n, I don't really know if it asks you for variables or numbers as the answer. Thank you!

Since you do not know what $m$ and $n$ are, your answer should be a "formula" that would work for any two $m$ and $n$ that satisfy the conditions of the problem.
