Bài này bạn viết hơi khó nhìn mk viết lại rồi đó mong bạn k cho mk
Bài 1:
6 cm2 = 600 mm2
43 km2 = 430 000 dam2
24 km2 = 2400 ha
236 000 hm2 = 2360 km2
15 km2 7 dam2 = 150 007 dam2
8 dam2 16 m2 = 816 m2
35 m2 7 dm2 = 3507 dm2
46 dam2 4m2 = 4604 m2
3602 m2 = 36 dam2 2m2
70 000 m2 = 7 hm2
960 m2 = 9 dam2 60m2
900 m2 = 9 dam2
Học tốt!!!
bạn thái hâu có copy ko đó
viết số thích hợp vào chỗ chấm:
4 dam2 24 m2 = .......m2 15 dam2 18 m2= ........ m2 12 dam2 24 m2 = ......... dam2 9 dam2 18 m2 = ....... dam2
mình cần rất gấp mong mọi người giúp đỡ
