‘Half-five’ is 90?...
Yeah, it's as Sangoma said based on vigesimal, so halvfems is a shortening of halvfemsindstyve which means half-to-five times twenty, half-to-five being 4.5. 4.5 * 20 = 90.
Historically the Danish numbering is based on 20, rather than the English 10. So 'fems' comes from 5 x 20, so halvfems is 90
And I could write it down for the first try, with only one typo for, without ever seeing it before! Very proud of myself :D
Why is it incorrect to say "We run ninety time in one year?"
In English we would use the plural since 90 > 1
That's what I meant to type, sorry. My question was actually about the "in one year" vs. "in a year." I typed "in one year" and it was marked incorrect.
Sorry - I didn't notice that, but mostly because I also would have thought 'one year' was acceptable, although maybe less common in this context than 'a year'.
Halvfems = 90 so "we run 90 times in a year" should be correct and not marked wrong.
