"Eight hundred million, nine hundred million, one billion"
Translation:Вісімсот мільйонів, дев'ятсот мільйонів, один мільярд
Forgive me, I'm going to have a tough time getting my question across. Why aren't there two correct answers here, the one that has mil'yoniv and the one that has mil'yony?
I don’t think «вісімсот мільйони» is grammatical. But maybe there’s some other structure? We don’t see what options you were presented with, so we can’t say much about them/
