  • (4 x (- 7) x 3) / (3 x 5 x 11)
    = (4 x (- 7)) / (5 x 11)
    = - 28 / 55

    (8 x (- 3)) / (15 x 2)
    = - (4 x 2 x 3) / (3 x 5 x 2)
    = - 4 / 5

    ( - 9 x 11) / (3 x 44)
    = - (3 x 3 x 11) / (3 x 11 x 4)
    = - 3 / 4
  • 4x(-7)x3/3x5x11
    =-28x3/15x11
    =-84/165
    =-28/55

    8x(-3)/15x2
    =-24/30
    =-4/5

    (-9)x11/3x44
    =-99/132
    =-3/4
