Question 1
(6a/8b) x (12d/10c)
= 72ad / 80bc
= (9ad) / 10bc
Question 2
= (- a² b) / (b² c) x (b² c²) / (a² c)
= - (a² b³ c²) / (a² b² c²)
= - b

I'm not going to answer this question for you because I don't see why I should do your homework for you. I will give you a hint. You have here a division divided by another division. It is much easier to see what to do if you multiply by the invert of the second division.
So that (a/b) / (c/d) = (a/b) * (d/c)

you have to flip the second fraction and then multiply arcross.
1.) i got
82ad/80bc which simplifies to
41ad/40bc
2.) i got
-a^2 b^3 c^2/ a^2 b^2 c^2
