3:2=1,5 (Yes "," as in "one comma five", not the american "." so not "one point five")

In ratio; 10,1:1 "ten comma one to one (used f. inst. in engine comprerssion ratio).

Same here in Italy.

Just curious: when speaking, does one actually say "one comma five" (though obviously in your native tongue), or perhaps "one decimal five" ?

And I think it's English "one point five" not American, though being American, I am not sure.
