"My brother and sister sing."
Translation:Min bror og søster synger.
What about if you have one brother and two sisters? I'm not a native English speaker but I guess one could say "my brother and sisters". In Danish can you say "Mine bror og søstre"? or do you have to repeat the possessive (first "min", second "mine")(repeating is what you should do in French, my native language, so that's why I'm asking)
