1km = 1000m       1m = 1000mm

1hm = 100m          1m = 100cm

1dam = 10m          1m = 10dm

1km = 10hm          1dm = 100mm

1hm = 10dam       1cm = 10mm

1hm = 100m

1 m = 10dm

1 dam = 10m

1 m = 100cm

1hm = 10dam

1cm = 10mm

1km = 1000m

1m = 1000mm

giải:

1hm = 100m

1 m = 10dm

1 dam = 10m

1 m = 100cm

1hm = 10dam

1cm = 10mm

1km = 1000m

1m = 1000mm

1 dm = 10 cm

1m = 1000 mm

1hm = 100m

1cm = 10 mm

20 dm = 2000 mm

mỗi đơn vị gấp nhau 10 lần,bn cứ thế làm nhé.

hok tốt!

1 dm = 10 cm

1 m = 1000 mm

1hm = 100 m

1 cm = 10 mm

20 dm = 200 mm

học tốt!!!

1km = 10 hm

1m = 10 dm

1km =1000 m

1 m =100 cm

1 hm =10 dam

1 m = 1000 mm

1hm =100 m

1 dm =10 cm

1 dam =10 m

1 cm =10 mm.

de the

1 dam = 10 m    5 dam = 50 m    1hm = 10 dam

1hm = 100 m    3hm = 300 m    5hm = 50 dam

1cm = 10 mm    2m = 20 dm    3m = 300 cm

bó tay

1/10hm

2/10dam

3/10m

4/100m

5/100mm

7/30m

8/600m

9/70dam

10/50hm

cho xin

1m=0,001 km

1 km = 1000 m

1 hm = 100 m

1 dam = 10 m

1 m = 10 dm

1 dm = 10 cm

1 cm = 10 mm

1 m = 0,001 km

1 km = 1000 m

1 hm = 100 m

1 dam = 10 m

1 m = 10 dm

1 dm = 10 cm

1 cm = 10 mm

1m=0.001km

1km=1000m

1hm=100m

1dam=10m

1m=10dm

1dm=10cm

1cm=10mm

mình nhanh nhất nha
