3 m + 20 cm = 300 cm + 20 cm = 320 cm

7 m + 400 cm = 7 m + 4 m = 11 m

3 m + 2000 mm = 3 m + 2 m = 5 m

5 000 m + 7 km = 5 km + 7 km = 12 km

980 hm + 78 000 m =

8 m - 2 450 mm = 800 cm - 245 cm = 555 cm

70 km - 45 000 m = 70 000 m - 45 000 m = 25 000 m

500 cm - 2 m =500 cm - 200 cm = 300 cm

8 m - 155 cm = 800 cm - 155 cm = 645 cm

900 cm - 370 mm = 9000 mm - 370 mm = 8 630 mm

8 x 35 hm = 280 hm = 28 km
