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

viết phan số hoạc hỗn số thích hợp vào chỗ chấm
3m2 45dm2 = ................m2
2km2 13 hm2 = ..............km2
47 dm2 =........................m2
83hm2 =........................km2
các bạn trả lời nhanh giúp mh với mh tích cho nhé
3 45/100m2; 2 13/100 km2; 47/100m2; 83/100 km2
3m2 45dm2 = 3 và 45/100 m2
2km2 13 hm2 = 2 và 13/100 km2
47 dm2 = 47/100 m2
83 hm2 = 83/100 km2
h cho mình nếu đúng nha
đáp án lần lượt là : 3 9/20 2 13/100 47/100 83/100
k mik nha
1km2 = ...m2

Nhanh giúp em với ạ.T-T
1km2 = 1000000 m2
50000 cm2 = 5 m2
1km2 305 m2 = 1000305 m2
3/ 10 m2 =30 dm2
k cho mình nha bn
