Question

divide and simplify: 5w-45/77 divided by w-9/121w

Answer 1

I understand the reciprocal, just do not understand how to deal with the Ws.

Answer 2

\[5w-45/77\div by 121w/w-9\]

Answer 3

\[(5w-45)/77 * 121w/(w-9)\]

\[121w(5w-45)/77(w-9)\]
if you look at the term 5w-45 it is really 5(w-9), and you can cancel 11 from both 121 and 77 so when you simplify you should get 55w/7
