                Eliminate the complex fractions
(5/8)/(-2/3)
(x^-1+y^-1)/(x+y)
(1/x+1/y)/(x+y) (xy/xy/)
I was trying to find the lcd for the first one but couldn't figure it out. For the second one, I got to as far as getting the reciprocal of the numerator and then multiplying by xy but I wasn't sure if that was right.

    (5/8)/(-2/3)
= (5/8)(-3/2)
= -15/16
(x^-1+y^-1)/(x+y)
= (1/x + 1/y)/(x+y)
= ((x+y)/(xy))/(x+y)
= 1/(xy)
    
= (5/8)(-3/2)
= -15/16
(x^-1+y^-1)/(x+y)
= (1/x + 1/y)/(x+y)
= ((x+y)/(xy))/(x+y)
= 1/(xy)

    So the first one, all I had to do was divide it normally? Do I do that if there are no lcd's for problems like that?

    you only need an lcd if you are adding fractions with unlike denominators.
Multiplication and division just work on the tops and bottoms separately.
