59?
How does nioghalvfems make 99?
The graphic is correct. "Halvfems" is shorthand for "halvfemsindstyvende" which roughly means; halfway to the fifth twenty. So 4,5 or 4-1/2 "twenties" so 90. But nobody rally thinks about that. To most Danes "halvfems" is just the name for 90, just like ninety is in English...
It should rather be 9 + (5 - 1/2) * 20. Halvfems is halfway from 4 to 5, but the 5 is the value explicitly mentioned
Yes. That is what i said? "Halfway to the fifth" which i clarified to mean 4,5 in this context, so as to not be confused to mean 2,5.
Yeah 5-1/2 is 4.5, but the word "fems" is short for femsindstyvende, which means 5x20, so writing it out as (5-1/2) rather than 4.5 matches the word halvfems more closely. Could also write it out as (-1/2 + 5) i suppose
Not Dane here but I know this:
"fems" is "five twenties"
"halvfems" is "halfway (between 4*20 and) 5*20" = 90
But don't forget that 100 has its own word and isn't fems, still 90 is halvfems.
