    Bonjour

    Calculer.

    F= 11/6 - (-3/4 - 5/6)

    F = 11/6 - [(-3 x 3)/(4 x 3) - (5 x 2)/(6 x 2)]

    F = 11/6 - (-9/12 - 10/12)

    F = 11/6 - (-19/12)

    F = (11 x 2)/(6 x 2) + 19/12

    F = 22/12 + 19/12

    F = 41/12

    G= (4/21 - 3/7) - (3/10 - 8/15)​

    G = (4/21 - (3 x 3)/(7 x 3)) - [(3 x 3)/(10 x 3) - (8 x 2)/(15 x 2)]

    G = (4/21 - 9/21) - (9/30 - 16/30)

    G = (-5/21) - (-7/30)

    G = (-5/21) + 7/30

    G = (-5 x 10)/(21 x 10) + (7 x 7)/(30 x 7)

    G = (-50/210) + 49/210

    G = (-1/210)
