2.
a)6m=6000mm
  12dm=1200mm
  37cm=370mm
b)19km=19000m
   45dam=450m
   63km=6300dam
c)250dm=25m
   3200cm=32m
   4700mm=47dm

3.
28000dm=280dam
28000dm=280000cm
28000dm=28hm
28000=2800m

5.
a)53m
b)2020m
c)20070m
d)32m
e)15m
f)7m

Spun ca cele doua sunt gresite, pentru ca eu, personal, nu cunosc multiplu de km mai mare doar de 10 ori...

Answer 2

2 .
6 m = 6000 mm
12 dm = 1200 mm
37 cm = 370 mm

19 km = 19000 m
45 dam = 450 m
63 km = 6300 dam

250 dm = 25 m
3200 cm = 32 m
4700 mm = 47 dm

3.
28 000 dm → 280 dam
28 000 dm → 280 000 cm
28 000 dm → 28 hm
28 000 dm → 2 800 m

4.
20 dam
13 m
5 dam

12 km
72 m
gresit !

8000 m
36000 m
13000 cm

9 hm
gresit !
70 km

5.
a. 4 dam + 13 m = 53 m
b. 2 km + 2 dam = 2020 m
c. 20 km + 7 dal = 20070 m
d. 300 dm + 200 cm = 32 m
e. 120 dm + 3000 mm = 15 m
f. 20 dm + 500 cm = 7 m
