Ok... I think this is what you are trying to do:
9p / 7q^-2 ÷ 2r^-3 / 5
1) Let's clean up the negative exponents. I'm going do work on each fraction individually
9p / 7q^-2 = 9p / 7 [1 / q^2] = 9p/7 * q^2 = 9pq^2 / 7
2r^-3 / 5 = 2/5 *r^-3 = 2/5 * 1/r^3 = 2 / (5r^3)
The problem is now: 9pq^2 / 7 ÷ 2 / (5r^3)
2) Change division to multiplication: 9pq^2 / 7 * (5r^3) / 2
3) Finish multiplying: (45 pq^2r^3 ) / 14
I think this matches your answer.
The sequence of steps are pretty flexible. You could have done them in a different order than I did and still got the right answer.
