  • Exercice 2

    a= 2/3 + 1/8
    a= 16/24 + 3/24
    a= 19/24

    b= -2/5 + 3/4
    b= -8/20 + 15/20
    b= 7/20

    c = - 5/7 - 3/2
    c = - 10/14 - 21/14
    c = - 31/14

    D= 4/7 - 4/5
    D = - 8/35

    E = 3 - 5/7
    E = 21/7 - 5/7
    E = 16/7

    F = -2 - 3/43
    F = - 8/4 - 3/4
    F = - 11/4
