Questions & Answers about Per trovare la metà, deve calcolare la frazione esatta.
Why use la metà instead of mezzo for 'the half'?
Why do we need per before trovare? Doesn't trovare already mean 'to find'?
Yes, trovare means 'to find,' but when an infinitive verb is used to express a purpose or goal ('in order to find'), Italian requires the preposition per.
Could deve mean someone other than 'he'?
Yes. Deve is the third-person singular form of the modal verb dovere (must). Depending on the broader context, it could also mean 'she must' or the formal 'you must' (Lei deve).
