roflmao, everyone who clicked the discussion thread for this was thinking the same thing
В данном случае "девушки". "Девочки" сранно звучит, будто речь об ребенке лет 12
For some reason I can't reply to posts, but одна is used with feminine words.
Attention! There is a wrong pronunciation of the word ложкА in this example. The right pronunciation is лОжка.
They mean the same thing.
I guess the declension of the word "один" must agree with the gender of the noun it precedes. Since "ложка" is feminine, "один" must change its declension to "одна".
No, it's because чашка is a feminine noun. With feminine nouns, две is used. Два is used with masculine and neuter nouns.
