The one you’re already using seems to work, if the output of the following is 
what you want:

\version "2.19.35"
\language "english"
 
threefour = {
  \time 9/8
  \set Staff.timeSignatureFraction = #'(3 . 4)
  \scaleDurations #'(3 . 2) {
    c''4 4 4   |
    c''4 4 4   |
  }
}

nineeight = {
  \time 9/8
  c''8 8 8 8 8 8 8 8 8   |
  c''8 8 8 8 8 8 8 8 8   |
}

\score {
  <<
    \new Staff \threefour
    \new Staff \nineeight
  >>
}

If that’s not what you want, let me know and I’ll try to help again.

Best,
Kieren.

p.s. When offering help, I’m always happy to create working examples that 
compile. But many others on the list aren’t, so to increase your chances of 
getting a response, you might consider always including a full working example 
which compiles.
