  • Bonsoir

    On va tout mettre au même dénominateur
    On mets tout /30

    4/15 —— 8/30 the first day
    2/5 ——— 12/30 the second day
    7/30 on the third day

    The total of the 3 days is 8/30 + 12/30 + 7/30 = 27/30

    No she hasn’t finished yet
    There is 3/30 of the pose to finish

    Bonne soirée
