Question

sacar una mala nota ____________________ vosotros

Answer 1

vosotros sacan una mala nota

Answer 2

Hello:
I'd say the best thing is for you to know the *endings* for the present simple (I assume this is the tense you need, don't you?).

Here is an example with the verb "cantar" (in English: "to sing"). (Note that "sacar" [which you need to answer your question] would have the same endings):

CANTAR (stem is CANT-)
yo - - cant + o (= canto)
tu - - cant + as (= cantas)
el/ ella - - cant + a (= canta)
nosotros/ nosotras - - cant + amos (= cantamos)
vosotros/ vosotras - - cant + ais (= cantais)
ellos/ ellas - - cant + an (= cantan)

So, with "sacar", we say "vosotros"...?

Hope this helps!
Blessings

P.S.: I am not including Spanish accents or tildes (which, "el" and "cantais" need) because an error seems to show up when I do.
