They are two, differents, actions that happened in the past.


Past Simple:
It is a complete action that happened in the past, that is, something started and finished at the moment of speaking.
It is composed by:
-Subject + verb in pat simple + rest of the sentence.

(the action began at 5:00 and finish at 6:30, it is a complete action).

Past Continuous:
It is an action that was interrupted by another action.
It is formed by:
-Subject + To be(in past simple) + verb+ing + rest of the sentence.
-To make the negative form and questions we use the verb "To be".
Ex:
