Odpowiedź :
40 mm = 40 : 10 cm = 4 cm
150 mm = 150 : 10 cm = 15 cm
300 mm = 300 : 10 cm = 30 cm
200 cm = 200 : 100 m = 2 m
1100 cm = 1100 : 100 m = 11 m
8000 cm = 8000 : 100 m = 80 m
70 dm = 70 : 10 m = 7 m
200 dm = 200 : 10 m = 20 m
1400 dm = 1400 : 10 m = 140 m
5000 m = 5000 : 1000 km = 5 km
21 000 m = 21 000 : 1000 km = 21 km
30 000 m = 30 000 : 1000 km = 30 km
