| |  Confused about this.
I have two questions which have a squared fraction in them. One is like this, (9/2)2 Divided by 3 3/2 and the other is (5/2)2 - 12/20. My question is...how do you work with the squared fractions? I am totally lost and any help is appreciated.
Edit: I've also ran into another question which I am having trouble with. This question is (- 25/24) x (36/30). The '-' in the first fraction is equal with the / paper meaning the whole fraction is negative I believe? Anyway I can't remember how to reduce the fractions so I can multiply.

so in particular, 
you could also recall that you square something is to multiply it by itself

So the squared fractions would be (81/4) and (25/9) ? |

if it is hard to find common denominators, note that the product of the denominators is always one. it might not be the smallest, but you can simplify your answer when done
