a) 12 hm - 3 200 cm + 730 dam = 8 468 m
= 1 200 m - 32 m + 7 300 m =
= 1 168 m + 7 300 m =
= 8 468 m

b) 130 hm + 12 000 m - 800 dam = 17 km
= 13 km + 12 km - 8 km =
= 25 km - 8 km =
= 17 km

c) 13 000 mm + 79 hm - 480 dm = 7 865 m
= 13 m + 7 900 m - 48 m =
= 7 913 m - 48 m =
= 7 865 m

d) 31 km + 45 hm - 700 m = 3 480 dam
= 3 100 dam + 450 dam - 70 dam =
= 3 550 dam - 70 dam =
= 3 480 dam
