Questions & Answers about Du måste halvera mängden socker.
How is the verb halvera related to the fractions we are learning?
Halvera is a verb meaning "to halve" or "to cut in half". It is built from the same root as en halv (the fraction "a half") and hälften (the proportion "the half").
Why isn't there a word for "of" between mängden and socker?
In Swedish, you generally do not use a preposition like av (of) when expressing a measurement or quantity of a substance. You simply put the amount noun right next to the substance noun. So, "the amount of sugar" is just mängden socker, similar to how "a glass of milk" is ett glas mjölk.
Why is mängden in the definite form here?
Why does halvera end in an -a here instead of being conjugated?
It follows the modal verb måste (must). In Swedish, just like in English, a modal verb is followed by the main verb in its infinitive (dictionary) form, which is halvera.
