a) 1m = 10dm = 100cm = 1000mm
1km = 1000m
1kg = 1000g
1 tấn = 1000kg
b)Sửa câu b: 1m =1/10dam = 0,1 dam
1m = 1/1000km = 0,001km
1g = 1/1000kg = 0,001kg
1kg = 1/1000tấn = 0,001tấn
a)1m=10dm=100cm=1000mm
1km=1000m
1kg=1000g
1 tan=100kg
b)1m=0,001=\(\frac{1}{1000}\)km
1g=\(\frac{1}{1000}\)=0,001kg
1kg=\(\frac{1}{1000}\)tan=0,001 tan
