Why is quaranta feminine, when the thing it is referring to - piatti - is masculine? Surely it is not in reference to scatola?
As far as I know, "uno" is the only number that changes gender according to what it's describing. The rest aren't feminine or masculine, they only have one form.
"We have forty plates in the carton" is wrong?
Yeah, scatola = box ( or tin, can according to this http://en.wiktionary.org/wiki/scatola). But it's more popular here in Duolingo that you use box
that is one heavy box
That's a big box!
"We have" was corrected for "we have got". Come on...
why quaranta piatti, but venti cavalli
Posso dire 'abbiamo 40 piatti IN scatola '?
