TIL that it not French with the weirdest way to count. I still don't really get the Danish way. Even with your explanation.
Itβs not really an explanation, just a table where I leave the linguistically inclined to figure it out. The point is, the βsβ at the end is short for βΓ20β and βhalf fifthβ is short for βββββ = 4Β½ (four and half of the fifth).
