"Minha mãe e meu pai são professores."

Translation: My mother and my father are teachers.

[CarolinaAl99]

I wrote "a minha mãe e o meu pai são professores". That is the correct portuguese in Portugal (they are teaching the brazilian kind, but I don't think it's fair).

[PHScanes]

Both are correct in the two countries...

[Danny.Roque]

I wrote that too and they corrected it now :)

In English it would be more natural to say "my mother and father are both teachers."
