Explicație pas cu pas:
a) 2 km = 20 hm = 200 dam
b) 30 km = 30000 m
c) 10 km = 100 hm
d) 300 km = 3000 hm = 30000 dam
e) 8 km = 80 hm = 800 dam
f) 3000 m = 300 dam = 30 hm
g) 30 dam = 300 m
h) 300 dam = 30 hm
i) 15000 dm = 1500 m = 150 dam = 15 hm
j) 8500 cm = 850 dm = 85 m
k) 4000 dm = 400 m = 40 dam = 4 hm
l) 2500 mm = 250 cm = 25 dm
