    u+c = 60

    u = 2/3 c

    u:c = 2:3

    (u+c):u = (2+3):2

    60:u = 5:2

    u = 60*2/5 = 24

    c = 60-24 = 36

    U = utilitarie

    C = coupè

    U + C = 60

    U = 2/3 C

    allora

    2/3 C + C = 60

    5/3 C = 60

    C = 3/5 * 60

    C = 36

    U = 2/3 * 36 = 24

    OPPURE

    C = 60 : (2+3) x 3 = 60 : 5 x 3 = 12 x 3 = 36

    U = 60 : (2+3) x 2 = 60 : 5 x 2 = 12 x 2 = 24

    2/3+3/3=5/3=60----60:5/3=60x3/5=36=utilitarie----coupè=60-36=24
