    Đề không rõ mik vt 2 TH nhé.
    TH1:
    (-0,75 – 1/4) : (-5) + 1/15 – 1 ((-1)/15)
    = (-3/4 – 1/4) : (-5) + 1/15 + 1/15
    = (-1) : (-5) + 2/15
    = 1/5 + 2/15
    = 3/15 + 2/15
    = 5/15
    = 1/3
    TH2: 
    (-0,75 – 1/4) : (-5) + 1/15 – 1 ((-1)/15)
    = (-3/4 – 1/4) : (-5) + 1/15 + 5
    = (-1) : (-5) + 1/15 + 75/15
    = 1/5 + 76/15
    = 3/15 + 76/15
    = 79/15
