  • Bonsoir,

    1/5 = 1 x 5 / 5 x 5 = 5/25

    - 2/10 = - 2 x 10 / 10 x 10 = - 20/100 = 4 x - 5 / 4 x 25 = - 5/25

    40/100 = 4 x 10 / 4 x 25 = 10/25

    - 3/75 = 3 x - 1 / 3 x 25 = - 1/25

    45/125 = 5 x 9 / 5 x 25 = 9/25

    - 2/50 = 2 x - 1 / 2 x 25 = - 1/25

    3 = 3 x 25 / 1 x 25 = 75/25

    - 1/3 = Impossible
