Question

1. Realizează următoarele transformări:

a)

160 hm= m

3600 dm= cm

7100 dam= km

8 m= cm

1900 dm= dam

30 km și 7 hm = dam

b)

2000 ml= cl

100 dl= l= dal

800 cl= dl

50 l și 4 dl= dl

3 kl= hl= dal= l

5000 l= dal= hl= kl

c)

900 cg= g

200 mg= dg

cg= 6 dg

30 kg= dag= g

80 q= t= kg

78000 kg= dag= g

2. Calculează:

40 dag+ 100 g= g

300 g - 40 dg= g

8 m+ 4 dam= m

172 km+ 600 dam= km

700 cm - 70 mm= cm

15 hm- 410 m= dam

1 dam- 280 cm= dm

320 dal+ 830 dal= hl

40 cl+ 60 cl= l

900 dl+ 40 dl= l

690 hl+ 260 hl= kl

16 dal- 1700 cl= l

Answer 1

1.a)160 hm=160*100 m=16000 m

3600 dm=3600*10 cm=36000 cm

7100 dam=7100/100 km=71 km

8 m=8*100 cm=800 cm

1900 dm=1900/100 dam=19 dam

30 km si 7 hm=30*100 dam+7*10 dam=3000 dam+70 dam=3070 dam

b)2000 ml=2000/10 cl=200 cl

100 dl=100/10l=10 l=10/10 dal=1 dal

800 cl=800/10 dl=80 dl

50 l si 4 dl=50*10 dl+4 dl=500 dl+4 dl=504 dl

3 kl=30 hl=300 dal=3000 l

5000 l=500 hl=50 dal=5 kl

c)900 cg=9 g

200 mg=2 dg

60 cg=6 dg

30 kg=3000 dag=30000 g

80 q=8 t=8000 kg

78000 kg=7800000 dag=78000000 g

2. 40 dag+100 g=500 g

300 g-40 dg=296 g

8 m+4 dam=48 m

172 km+600 dam=178 km

700 cm-70 mm=693 cm

15 hm-410 m=109 dam

1 dam-280 cm=72 dm

320 dal+830 dal=115 hl

40 cl+60 cl=1 l

900 dl+40 dl=94 l

690 hl+260 hl=95 kl

16 dal-1700 cl=143 l
