Răspuns:

13 km + 400dm = 1700 dam

23 hm - 4000 dm = 190 dam

63 hm - 1300 cm = 6287 m

18 dm - 50 cm = 13 dm

Explicație pas cu pas:

13 km + 400dm = 1300 dam + 400 dam = 1700 dam

23 hm - 4000 dm = 230 dam - 40 dam = 190 dam

63 hm - 1300 cm = 6300 m - 13 m = 6287 m

18 dm - 50 cm = 18 dm - 5 dm = 13 dm
