  • b) 1 1/2 + 40% - 0,3 : 1/9

    = 3/2 + 40/100 -( 3/10 : 1/9)

    = 3/2 + 4/10 - (3/10 x 9/1)

    = 3/2 + 4/10 - 27/10

    = 15/10 + 4/10 - 27/10

    = - 8/10 = -4/5


    c) 1 1/2 x 40% + 0,3 : 1/9

    = (3/2 x 40/100) + ( 3/10 : 1/9)

    = (3/2 x 4/10) + ( 27/10)

    = 6/10 + 27 /10

    = 33/10 = 3 3/10


    d) 1 1/2 : 40% - 0,3 x 1/9

    = (3/2 : 40/100) - ( 3/10 x 1/9)

    = (3/2 x 10/4) - (1/30)

    = 15/4 - 1/30

    = 225/60 - 2/60

    = 223/60 = 3 43/60


    e) 1 1/2 + 40% x 0,3 : 1/9

    = 3/2 + 40/100 x ( 3/10 : 1/9)

    = 3/2 + (4/10 x (3/10 x 9/1))

    = 3/2 + (4/10 x 27/10)

    = 3/2 + 108/100

    = 3/2 + 54/50

    = 75/50 + 54/50

    = 129/50 = 2 29/50


    f) 1 1/2 - 40% : 0,3 x 1/9

    = 3/2 - (40/100 : 3/10) x 1/9

    = 3/2 - (4/10 x 10/3) x 1/9

    =3/2 - (4/3 x 1/9)

    = 3/2 - 4/27

    = 405/270 - 40/270

    = 365/270 = 1 19/54
