Answer:
Nandine faisait la lessive quand ses copines sont arrivées.
Mes parents dormaient quand l’horloge est tombée du mur.
Nous balayions la cuisine quand Hubert sortait la poubelle.
Vous jouiez ensemble quand nous avons quitté la maison.
Il rangait sa chambre quand son ami a appelé.
Step-by-step explanation:
Translation:
Nandine was doing the laundry work when her friends had arrived.
My parents were sleeping when the clock had fallen from the wall.
We were sweeping the kitchen when Hubert was taking out the trash.
You were playing together when we had left the house.
He was tidying up his room when his friend had called.
Note: Please check my answers for the 3rd and 4th one, I am unsure if "Hubert taking out the trash" and "leaving the house" are continuous actions in the past or not.
Hope this helps you! Merci :)
