500m = 5hm
13 000m = 13 km
1mm = 0,1 cm
1cm = 0,1 dm
1dm = 0,1 m
Bài 1: 1 km = 10 hm = 1000 m
1 hm = 10 dam = 0,1 km = 100 m
1 dam = 10 m = 0,1 hm
1 m = 10 dm = 0,1 dam
1 dm = 10 cm = 0,1 m
1 cm = 10 mm = 0,1 dm
1mm = 0,1 cm

b) 60 m = 6 dam
500 m = 5 hm
13 000 m = 13 km
c) 1mm = 0,1 cm
1 cm = 0,1 dm
