    2/5 - 3/5(10/9+20)=?
    2/5 - 3/5 ( 1 1/9 + 20)  = 2/5 - (3/5 x 21 1/9)
    2/5 - (3/5 x 190/9) =
    2/5 -( 570/15) =
    2/5 - 38 = 38 - 2/5 = 37 3/5   ????????? 

    2/5 - 3/5(10/9 + 20)


                  (10/9 + 180/9)


    2/5 - 3/5(190/9)


              -3/5(190/9)


                  -570/45


            2/5 -12 2/3


           6/15 - 12 10/15


            6/15 - 190/15


    -184/15


    -12 4/15


     OR, I could have subtracted........


    2/5 - 570/45


    18/45 - 570/45


    -552/45 = -552/45 / 3/3 


    -184/15


    -12 4/15


     

    is it


    A. -20


    b. -13 1/9


    c. -12 4/15


    d. -11 1/3

       2/5-3/5(10/9+20)


    = 2/5-2/3+12


    = 6/15-10/15+180/15


    = -4/15+180/15


    = 176/15
