Re: complex faction
Hello, dkarolasz!
Exactly where is your difficulty?
You know to divide by a fraction: invert and multiply . . .
\(\displaystyle \L\frac{\frac{w\,+\,3}{4w}} {\frac{w\,-\,3}{2w}} \;=\;\frac{w\,+\,3}{_2\not{4}\not{w}}\,\cdot\,\frac{\not{2}\not{w}}{w\,-\,3} \;=\;\frac{w\,+\,3}{2(w\,-\,3)}\)
