Wouldn't it sound more natural to say "A century is a/one hundred years" in English?
I agree that "A century is one hundred years" is perfectly correct. I have notified duolingo of the error.
Yes. I was marked wrong
a century has 100 years...not accepted
I think duo doesnt accept digits....
It is now accepted
But 'a century has hundred years' is not accepted. Duolingo requires the word 'a' or 'one' in front of 'hundred'.
You need the article because "hundred" is not exactly a number. We treat it more like a unit, so "one hundred" is the number, just like "one dozen" eggs or *a pound of flour"
I agree with dementati that in american english the translation would be "A century is a hundred year" though "has" is also correct it is less likely to be used.
