557) a)
8 000 m = 800 dam = 80 hm = 8 km
900 hm = 90 dam = 9 m
23 dam = 230 m = 2 300 dm = 23 000 cm
104 m = 1 040 dm = 10 400 cm = 104 000 mm
b)
5 000 mm = 500 cm = 50 dm = 5 m
18 000 dm = 1 800 m = 180 dam = 18 hm
55 000 cm = 5 500 dm = 550 m = 55 dam
37 hm = 370 dam = 3 700 m = 37 000 dm
558
3 hm si 2 dam = 300 m + 20 m = 320 m
75 km si 2 hm = 7 500 dam + 20 dam = 7 520 dam
30 m si 15 cm = 30 000 mm + 150 mm = 30 150 mm
17 000 mm si 50 dm = 17 m + 5 m = 22 m
200 m si 320 dam = 2 hm + 32 hm = 34 hm
320 cm si 1 300 mm = 32 dm + 13 dm = 45 dm
1 dam si 1 m = 1 000 cm + 100 cm = 1 100 cm
