2 / 5 ha = 10000 m2 : 5 x 2 = 4000 m2
1 / 4 km2 = 100 km2 : 4 = 25 ha
2000 ha = 2000 ha : 100 = 20 km2
333 ha 33 m2 = 3330000 m2 + 33 m2 = 3330033 m2
nhé !
mình học rồi
6,23m2 =...dm2 2,87km2 =...ha;
5,6257ha =...m2 4km2 114dam2 =...km2
3m2 26cm2 =...m2 2,5m2 =...dm2
Điền vào chỗ chấm 3 4km2 ......ha 215ha ........m24 5ha .....m2. 140000m2 ......ha1400ha ......km2
Bài 1: Điền số thích hợp vào chỗ chấm
16m2 23dm2 = ...........m2 631km2 7dam2 = ...........km2 8,54m2 = ...........m2 ……dm2
70dam2 2m2 = ...........dam2 4km2 7hm2 = ...........km2 2,15km2 = ...........km2 ……hm2
Help me pls question!
