Help

Have I transformed correctly active to passive sentence?

  1. Carthaginem, quam Scipio deleverat, Augustus restituit.
    Carthagino, quae a Scipie deleta erat, ab Augusto restituta est.


    And, can someone help me translate this:
  2. Pax est optima omnium rerum.
    Peace is (what ?).


    What does rerum mean?

Correctly transformed, except for some inaccuracies in the declension :

Carthago… a Scipione (symetrical errors… in using stems of 3rd declension nouns : sing nominative Carthago but in the other cases you add the ending to the stem Carthagin-, the same for Scipio, Scipion-)

And, can someone help me translate this:
2) Pax est optima omnium rerum.
Peace is (what ?).


What does > rerum > mean?

Plural genitive from res, rei “thing” : so “peace is the best of all things”

Thanks!
