  1. 1/2 . (-43/101) + (-1/3) – 1/6
    = -43/202+ (-1/3) – 1/6
    =-43/202 + (-2/6 ) – 1/6
    = -43/202 – 1/2
    =-43/202 – 101/202
    =-144/202
    =-72/101

  2. Giải đáp:
    1/2xx(-43)/101+((-1)/3)-1/6
    =1/2xx(-43)/101-1/3-1/6
    =(-43)/202-1/3-1/6
    =(-129)/606-202/606-101/606
    =(-129-202-101)/606
    =(-432)/606=(-72)/101
