57hm=570dam
39hm=390dam
107hm=1070dam

79km=7900dam
330km=33000dam
800km=80000dam

25km=25000m
890km=890000
6km=6000m

230hm=2.30km
4500hm=450km
9070hm=907km
57 hm = 57 x 10 dam = 570 dam
390 dam = 390 : 10 hm = 39 hm
107 hm = 107 x 10 dam = 1070dam

7 900 dam = 7 900 : 100 km = 79 km
330 km = 330 x 100 dam = 33 000 dam
800 km = 800 x 100 dam = 80 000 dam

25 km = 25 x 1 000 m = 25 000 m
890 km = 890 x 1 000 m = 890 000 m
6 000 m = 6 000 : 1 000 m = 6 km

230 hm = 230 : 10 km = 23 km
450 km = 450 x 10 hm = 4 500 km
907 km = 907 x 10 hm = 9 070 hm
