Răspuns:

a) 180 dam+320 dam=500 dam=5000 m

500 dam ---m---> 500×10=5000 m

1000 m-50 dam=100 dam-50 dam=50 dam

1000 m ---dam---> 1000:10=100 dam

6×250 dam=1500 dam=150 hm

1500 dam ---hm---> 1500:10=150 hm

b) 4 m+ 33 dm=40 dm+33 dm=73 dm

4 m ---dm---> 4×10=40 dm

42 m-30 dm=42 m-3 m=39 m

30 dm ---m---> 30:10=3 m

6×220 dm=1320 dm=132 m

1320 dm ---m--->1320:10=132 m

c) 17 dm+19 cm=170 cm+19 cm=189 cm

17 dm ---cm---> 17×10=170 cm

415 dm-70 cm=415 dm-7 dm=408 dm

70 cm ---dm---> 70:10=7 dm

80 mm:2=40 mm= 0.04 m

40 mm ---m---> 0.04 m

Sper te-am ajutat!
