  • Bonsoir,

    A = 3/7 * (7/3 - 5/6)

    A = 3/7 * (14/6 - 5/6)

    A = 3/7 * 9/6

    A = 3/7 * 3/2

    A = 9/14

    B = 3/7 * 7/3 - 5/6

    B = 21/21 - 5/6

    B = 1 - 5/6

    B = 6/6 - 5/6

    B = 1/6

    C = 12 * (1/3 - 1/6)

    C = 12 * (2/6 - 1/6)

    C = 12 * 1/6

    C = 12/6 = 2

    D = 12 * 1/3 - 1/6

    D = 12/3 - 1/6

    D = 4 - 1/6

    D = 24/6 - 1/6

    D = 23/6
