Answer 1

1) a) 9m=90dm=900cm

4m=40dm =4000mm

B) 5000mm =500cm =50dm

700cm =70dm =7000mm

C) 800dam =80hm =8km

6km =60hm =600dam

2) a) 220dam +480dam =7000m

1000m-5hm =50dam

6x150dam =900dam

B) 4m+45dm =85dm

72m-20dm =70m

6x220cm =132dm

C) 12dm+20cm=140

725dm-40cm=721dm

80mm:2=4cm

3) A) 8m=80dm

10m=100dm

B) 5m=500cm

3000dm=30dam

C) 2000cm=2dam

8000dm=800m

D) 9hm=900m

7m=700cm

4)8x10m=80m

80m=8dam

40dam-8dam=32dam

32dam:4dam=8(bucati)

5) 50dm=5m

1/2dam=0,5dam=5m

400cm=4m

0,25hm=25m

100cm=1m

1m,4m,5m,5m,25m
