Please check these plurals!

I'm sure Rosetta Stone has these wrong, can somebody please check ...

It says 14 cups is Четырнадцать чашек, I say it should be чашки.

It says 13 eggs is тринадцать яиц, I say it should be яйца.

Thanks,
Lindsay

Numbers above 5 take the gen. plural like in your examples. The exception is compound numbers ending in 1-4 (e.g. пятьдесят один, семьдесят три, восемьдесят четыре, шестьдесят два - 51, 73, 84 62) which take the gen. singular.

hello, Lindsey,

Rosetts Stone is right.

In the phrases "cardinal numeral + plural noun" , the form of the plural noun will vary depending upon the cardinal numeral:

1) after the cardinal numerals "2, 3 and 4" the plural noun will actually be in the form of SINGULAR GENITIVE:

Nom. Одна чашка -- Gen. Не хватает одной чашки

- ДВЕ чашки, тарелки, миски, ручки, девушки (herre all nouns are feminine),

- ТРИ чашки, тарелки, миски, ручки, девушки,

- ЧЕТЫРЕ чашки, тарелки, миски, ручки, девушки.


2) after the cardinal numerals "5, 6 etc" the plural noun will be in the form of PLURAL GENITIVE:

- ПЯТЬ чашек, тарелок, мисок, ручек, девушек,

- ШЕСТЬ /СЕМЬ/ ВОСЕМЬ/ ДЕВЯТЬ / ДЕСЯТЬ / ДВАДЦАТЬ / СТО чашек, тарелок, мисок еtc.

OK, I didn't realise that the "teens" were all GP, even 11, 12, 13, 14. Thanks, I understand it now :)
