  1. 0,01 kg = 0,01 xx 1000 = 10g
    0,009 kg = 0,009 xx 1000 = 9g
    0,052 kg = 0,052 xx 1000 = 52g
    GT:
    1 kg = 1000g
     

  2. 0,01kg = 10g
    Vì 1kg = 1000g
    0,01 × 1000 = 10g
    0,009 kg =9g
    Vì 1kg = 1000g
    0,009 × 1000 = 9g
    0,052 kg =52g
    Vì 1kg = 1000g
    0,052 × 1000 = 52
