  • Bonsoir


    les calculs sont dans le désordre je te laisse mettre les couleurs car pas très lisible le codage :

    3/12 + (5/2 - 3/4)

    = 3/12 + (5 x 6)/(2 x 6) - (3 x 3)/(4 x 3)

    = 3/12 + 30/12 - 9/12

    = 24/12

    = (12 x 2)/12

    = 2


    (2 + 9)/(5 - 3)
    = 11/2

    = 5,5


    7/12 + 9/4 - 5/6

    = 7/12 + (9 x 3)/(4 x 3) - (5 x 2)/(6 x 2)

    = 7/12 + 27/12 - 10/12

    = 24/12

    = 2


    7/3 - 2/3 x 7/8

    = 7/3 - (2 x 7)/(3 x 8)

    = 7/3 - 7/12
