a) 23 m = 230 dm ; 305 dm =3050 cm ; 1065 cm = 10650 mm
b) 7 km =7000 m ; 12 hm = 1200 m ; 234 dam =2340 m
c) 250 m = 25 dam ; 5400 m = 54 hm ; 12000 m = 12 km
d) 150 mm = 150 cm ; 2000 mm = 20 dm ; 10000 mm = 10 m
Viết số thích hợp vào chỗ chấm :
a) 23 m = ..230... dm ; 305 dm = ...3050..... cm ; 1065 cm = ....10650..... mm
b) 7 km = ..7000... m ; 12 hm = ....1200..... m ; 234 dam = ...2340...... m
c) 250 m = ..25... dam ; 5400 m = ....54... hm ; 12000 m = .....12.... km
d) 150 mm = ....15... cm ; 2000 mm = ...20... dm ; 10000 mm = ....10.... m
