Halvfjerds for 70 but yes. Firs is 80 though, so that doesn’t make in much easier.
Fjerde = fourth, fire = four. That makes “half to the fourth” become “halv til fjerde” or “halvfjerds” while “four times twenty” becomes “firsindstyve” and shortened to new Danish “firs”
You also use halv tres (50) and halv firs (70) don’t you?
