Question

a)1 km=   hm 

1hm=    dam

1dam=   m

1km=    m

b)1mm=   cm

   1dm=     m

   1cm=        m

 1mm=    m

Answer 1

a)\(1km=10hm\)

\(1hm=10dam\)

\(1dam=10m\)

\(1km=1000m\)

b)\(1mm=\frac{1}{10}=0,1cm\)

\(1dm=\frac{1}{10}=0,1m\)

\(1cm=\frac{1}{100}=0,01m\)

\(1mm=\frac{1}{1000}=0,001m\)

Answer 2

1km=10hm

1hm=10dam

1dam=10m

1km=1000m

b)1mm= 1/10 cm

1dm=1/10 m

1cm=1/100m

1mm=1/1000 m

Answer 3

a) 1km= 10hm

1 hm= 10dam

1dam= 10m

1km = 1000m

b) 1mm= 0,1cm

1dm= 0,1 m

1cm= 0,01m

1mm= 0,001 m

Answer 4

a) 1km = 10hm

1hm = 10dam

1dam = 10m

1km = 1000m

b)1mm = 1/10

1dm = 1/10m

1cm = 1/100

1mm = 1/1000m

Answer 5

a) 1 km = 10 hm

1 hm = 10 dam

1 dam = 10 m

1 km = 1000 m 

b) 1 mm = 0,1 cm

1 dm = 0,1 m

1 cm = 0,01 m

1 mm = 0,001 m

Answer 6

a) 1 km = 10hm

1hm = 10 dam

1 dam= 10 m

1km = 1000m

b) 1mm = 1/100cm

1dm = 1/10m

1cm=100m

1mm= 1000m

CHÚC BẠN HỌC TỐT!!!!

Answer 7

mình nhầm 1cm= 1/100m

1mm = 1/1000m 

Xin lỗi bạn.

Answer 8

1 km = 10 hm

1 hm = 10 dam

1 dam = 19 m

1 km = 1000 m

1 mm = 1/10 cm

1dm = 1/10 m

1 cm = 1/100 m

1mm = 1/1000m
