16hm+25dam = 1600m + 250m = 1850m
550cm + 2000mm = 55dm + 20dm = 75dm
2km + 4hm = 200dam + 40dam = 240dam
4hm+5dam = 4000dm + 500dm = 4500dm
65dam+235dm = 65000cm + 2350cm = 68500cm

1. 1.600 m + 250 m= 1.850 m
2. 55 dm + 20 dm= 75 dm
3. 200 dam + 40 dm= 240 dam
4. 4.000 dm + 500 dm= 4.500 dm
5. 65.000 cm + 2.350 cm= 67.350 cm
