Answer 2

Răspuns:

1.1 hm=100 m

17 hm=1700 m

1 dam=10 m

19 dam=190 m

70 km=70000 m

100 dam=10 hm

19 hm=1900 m

700 m=7 hm

1 kg=10 hg

17 kg=170 hg

14 kg=1400 dag

80 kg=80000 g

29 kg=290 hg

700 kg=700000 g

6 q=600 kg

9 t=9000 kg

8000 kg=8 t

70 dl=7 l

700 cl=7 l

7000 ml=7 l

7 dal=70 l

8 hl=800 l

9 kl=9000 l

40 cl=4 dl

60 ml=6 cl

90 dl=9 l

2.a)4 km = 4000 m

3 hm=300 m

4000m+300 m=4300 m

7 dam=70 m

70 hm=7000 m

70 m+7000 m= 7070 m

6 km=6000 m

330 dam=3300 m

6000 m+3300 m=9300 m

3000 mm=3 m

2000 mm=2 m

3 m+2 m=5 m

800 cm=8 m

7000 mm=7 m

8 m+7 m=15 m

80 dm= 8 m

400 cm= 4 m

8 m+4 m=12 m

5000 mm=5 m

400 cm= 4 m

5 m+ 4 m= 9 m

b)17 t=17000 kg

18 q=1800 kg

140 kg+17000 kg+1800 kg=18940 kg

800 dag=8 kg

80 hg=8 kg

8 kg+8 kg+8 kg=24 kg

9000 g=9 kg

800 dag=8 kg

70 hg=7 kg

9 kg+8 kg+7 kg=24 kg

15 t=15000 kg

15000 kg+ 14 g+80 kg=15080 kg,14 g

3000 g= 3 kg

200000 dg=20 kg

300000 cg=3 kg

3 kg+20 kg+3 kg=26 kg

c)14000 ml=14 l

800 cl=8 l

14 l+8 l=22 l

900 cl=9 l

80 dl=8 l

9 l+8 l= 17 l

70 dl=7 l

400 cl=4 l

7 l+4 l=11 l

8000 ml= 8 l

20 dl=2 l

8 l-2 l=6 l

7 kl=7000 l

7 hl=700 l

7000 l+ 700 l=7700 l

9 kl=9000 l

6 hl=600 l

9000 l-600 l=8400 l

8 kl=8000 l

3 hl=300 l

8000 l-300 l=7700 l
