..... bn tự làm tiếp nhé

7000m =7km     630cm = 63dm

8500cm = 85m    67 000mm = 67m

7000m= 7km

k mk nha

a) 148 m = 1480 dm

531 dm = 5310 cm

92 cm = 920 mm

89 dam = 890 m

76 hm =760 dam

247 km = 2470 hm

b) 7000 m = 7 km

8500 cm = 85 m

630 km = 63000 dm

67000 mm = 67 m

148m = 1480 dm

531 dm = 5310 cm 

92 cm = 920 mm

89 dam = 890 m

76 hm = 760 dam

247 km = 2470 hm

b , 

7000m = 7 km

85 cm = 85 m 

630 km = 63 / 1000 dm

67000 mm = 67 m

50000km=5000000dam=50000000000cm

0,00008m=0,0000008hm=0,08mm

chuc bạn hoc tot!

\(\dfrac{1}{10}hm^2=1000m^2\)

\(\dfrac{3}{5}hm^2=6000m^2\)

3/5hm2=6000m2

0,35 dm = 0,000035 km

3 cm = 0,00003 km

14,75 mm = 0,0001475 hm

3,2 km 53 cm =   320 0053m

54 hm 49 cm = 5400049 m

0,000035km

0,000003km

0.000035

0.00003

0.0001475

3.2 km= 3200m

vậy 3200m 53cm= 3200,53m

54hm= 5400m

Vậy 5400m 49cm= 5400,49
