I have quite a bit on my website about complex fractions such as this, especially on my MATH IN LIVING COLOR pages. To see my website, click on my tutor name "Rapaljer" anywhere in algebra.com. From my homepage, click on "Math in Living Color", and look for either "Intermediate Algebra," Chapter 2, or "College Algebra," Chapter 1. These are actually the same exercises.
