Bài 1: Viết số thích hợp vào chỗ chấm:
a) 3m2 24dm2 = ……….dm2 b) 1km2 500 000m2 = ……….............m2
2m2 1dm2 = ………..dm2 2km2 345m2 = ……….............m2
1m2 2 345cm2 = ……….cm2
1m2 45cm2 = …………cm2
TL:
a) 3m2 24dm2 = 324dm2 b) 1km2 500 000m2 = 1 500 000m2
2m2 1dm2 = 201dm2 2km2 345m2 = 2 000 345m2.
1m2 2 345 cm2 = 10 345cm2
