"Quot puellas docetis?"

Translation: How many girls do you teach?

[Amrhilman]

May someone explain what are the differences between quot vs quanti in context to this sentence?

[PERCE_NEIGE]

Quot means you ask for "how many" as a number. So, a plural is required after this word. how many girls?

Quanti means you ask for an uncountable quantity, like "how big", "how large", "how much".

[MichaelBel419582]

if Quanti is meant for an uncountable quantity, why is it used for price, which is clearly countable (i.e. quanti constant)?

[Rae.F]

PERCE_NEIGE over-simplified things, and her answer is not entirely accurate.

quantus, a , um means "how great"
quot (indeclinable) means "how many"
quantus has a larger scope than quot and, in the plural, means "how many" as well.

Can someone explain why it is puellas and not puellae in this case? :)

[YafieAgha]

It uses the accusative case
