Questions & Answers about Żeby upiec ciasto, potrzebujesz półtorej szklanki mąki.
Why do we use półtorej here instead of półtora?
Półtorej is the special feminine form of 'one and a half'. You use it here because the noun it counts, szklanka (glass), is a feminine word. If you were counting a masculine or neuter noun, you would use półtora (for example, półtora jabłka - one and a half apples).
Why are the words szklanka and mąka written as szklanki and mąki?
Both are in the Genitive case. First, the number words pół, półtora, and półtorej always force the noun right after them into the Genitive case, turning szklanka into szklanki. Second, mąki is Genitive because it connects two nouns to mean 'of', translating to a glass of flour.
Does the verb potrzebujesz (you need) also affect the grammar here?
Yes, it does! The verb potrzebować (to need) always requires the thing you need to be in the Genitive case. So even if the fraction półtorej wasn't in the sentence, you would still say potrzebujesz szklanki (you need a glass) using the Genitive case.
