Perform the indicated operations and reduce all results to lowest terms. Assume the variables are restricted to values that prevent division by 0.
(x^2y^2)/(x^22xy+y^2) divided by (3x+3y)/(7x21)
Could someone please show me how to do this so I can do the rest of my homework? I don't understand this at all. Thank You

Damon,
(x^2y^2) = (x+y)(xy)
x^22xy+y^2 = (xy)(xy)
so when you divide the first by the second you get
(x+y)/xy)
Now work on the bottom
(3x+3y) = 3(x+y)
(7x21)= 7(x3)
Now turn that upside down and multiply by the numerator
7(x3) /3(x+y) * (x+y)/(xy)
(7)(x3)/3(xy)
