Complex Fraction Help.

[From: ] [author: ] [Date: 12-06-11] [Hit: ]
It could also be written as - ((x - y) / (x^2 y^2)), but I wouldnt consider that fully simplified.......
The Problem Says Simplify : 1/x-1/y/xy. I got x^2 y^2. But Thats Not One Of The Answers. Help Please.

-
(1/x - 1/y) / xy =
(1/x - 1/y)(xy) / (xy)(xy) =
(xy/x - xy/y) / (x^2 y^2) =
(y - x) / (x^2 y^2)

Is that one of the answers?

It could also be written as - ((x - y) / (x^2 y^2)), but I wouldn't consider that fully simplified.
