Answer 1

1 cm = 0,01 m

1)620 cm= 6,2m

1 dam = 10 m

2)73 dam = 730 m

1 dm = 100 mm

3)0,091 dm = 9,1 mm

1 dm = 0,001 hm

4)2470 dm = 2,47 hm

1 cm = 0,00001 km

5)2450000 cm = 24,5 km

1 km = 1000 m

6)4,9 km = 4900 m

7) 2,51 dm + 10mm = 25,1 + 1 = 26,1 cm

8) 1hm + 1 dam + 1dm = 100 + 10 + 0,1 = 110,1 m

9) 7,5 km - 3000000 mm = 750 - 300 = 450 dam

10) 570 mm - 0,0028 hm = 57 - 28 = 29 cm
