  1. Giải đáp:
    5,27+14,35+9,25= 28,87
    20,08+32,91+7,15= 60,14
    5,9:2+13,06= 16,01
    167:25:4= 1,67
     

  2. 5,27 + 14,35 + 9,25
    = 5,27 + (14,35 + 9,25)
    = 5,27 + 23,6
    = 28,87
    _____________________________
    20,08 + 32,91 + 7,15
    = 52,99 + 7,15
    = 60,14
    _______________________________
    5,9 : 2 + 13,06
    = 2,95 + 13,06
    = 16,01
    ________________________________
    167 : 25 : 4
    = 167 : (25 xx 4)
    = 167 : 100
    = 1,67
