    Giải đáp+Lời giải và giải thích chi tiết:
    (-5/12+7/4-3/8)-|4 1/2-7 1/3|-(1/4-5/2)
    =(-10/24+42/24-9/24)-|9/2 – 22/3| -(1/4-10/4)
    =23/24-|27/6 – 44/6|-(-9/4)
    =23/24-|-17/6|+9/4
    =23/24-17/6 +9/4
    =23/24-68/24+54/24
    =9/24
    =3/8

  2. (-5/12 + 7/4 – 3/8) – | 4 1/2 – 7 1/3| – ( 1/4 – 5/2)
    = (-10/24 + 42/24 – 9/24) – |9/2 – 22/3| – ( 1/4 – 10/4)
    = 23/24 – | 27/6 – 44/6| – (-9)/4
    = 23/24 – |(-17)/6|  + 9/4
    = 23/24 – 17/6 + 9/4
    = 23/24 – 68/24 + 54/24
    =9/24
    = 3/8
