Best ResponseYou've already chosen the best response.0Step 1 top line: add the two fractions 1/x and 1/y (you should get (x+y)/xy Step 2 bottom line: add the two fractions 3/x^2 and 5/y^2 to get (5x^2 + 3y^2)/x^2y^2 You should be OK from here

Best ResponseYou've already chosen the best response.0Remember when dividing by a fraction to turn it upside down and multiply, then cancel what you can and you're done

Best ResponseYou've already chosen the best response.0So I'm getting my final answer to be: x+y  8

Best ResponseYou've already chosen the best response.0mmmm...I get Step1 divided by Step 2 (x+y)/xy divided by (5x^2 + 3y^2)/x^2y^2 which is (inverting the bottom fraction) (x+y)/xy multiplied by x^2y^2/(5x^2 + 3y^2) cancel the xy top and bottom to get xy(x+y)/(5x^2 + 3y^2) let me know if you agree

Best ResponseYou've already chosen the best response.0So you're getting X+Y  5X^2+3Y^2 ?

Best ResponseYou've already chosen the best response.0No, top line is xy(x+y). Bottom line is OK

Best ResponseYou've already chosen the best response.0Wouldn't that factor out on the top then?

Best ResponseYou've already chosen the best response.0Not quite sure what you mean by 'factor out', but no, there's nothing more you can cancel or do. You could multiply out the top line as \[x^2y + xy^2\] if you want, but I assume you are to factor out fully so my answer is still \[xy(x+y)/(5x^2+3y^2)\]
