Well, its actually much more complicated than that.  Once you have a core,
theres a lot more design involved than just winding number of turns on the
core.

However just to answer your winding ratio question, if you had say 1VAC
input with a 100:1 winding ratio, than you would need 150 turns on the
secondary to get 15000VAC.  However, again you cannot just blindly go do
this.  There is a lot of design around what type and size core you really
need for the voltage, current, frequency etc... of the transformer you want
to make.
