Which of the following would be used to calculate a transformer's transformation ratio?
- Secondary turns / primary turns.
- Primary turns * secondary turns.
- Primary turns / secondary turns.
Explanation from PART66Online
The transformation ratio used to find the output is secondary turns divided by primary turns, since Vs = Vp x (Ns/Np). Multiplying the turns together has no physical meaning, and primary divided by secondary would give the inverse ratio, predicting the opposite of the actual voltage change.

Hello.
But I have other information: pdf-archive.com/2013/06/04/transformer
Actually if we are talking about the American version of turns ratio is used it is Primary:Secondary. English notation is Secondary:Primary.
