  1.  289/719 : (1/4 + 1/12 – 1/3) – 2011/2012
    = 289/719 : (3/12 + 1/12 – 4/12) – 2011/2012
    = 289/719 : 0 – 2011/2012
    = 0 – 2011/2012
    = -2011/2012

  2. Giải đáp:
     -(2011)/(2012)
    Lời giải và giải thích chi tiết:
    (289)/(719):((1)/(4)+(1)/(12)-(1)/(3))-(2011)/(2012)
    =(289)/(719):(3+1-4)/(3*4)-(2011)/(2012)
    =(289)/(719):(0)/(12)-(2011)/(2012)
    =(289)/(719)*0-(2011)/(2012)
    =-(2011)/(2012)
