Viết phân số thích hợp vào chỗ chấm:
1 m 2 = … … d a m 2 1 d a m 2 = … … h m 2
4 m 2 = … … d a m 2 7 d a m 2 = … … h m 2
38 m 2 = … … d a m 2 52 d a m 2 = … … h m 2
Viết phân số thích hợp vào chỗ chấm:
1 m 2 = 1 100 d a m 2 1 d a m 2 = 1 100 h m 2

4ha -25 dam2 =...dam2
7dm2 +42 mm2=....mm2
Trả lời
4ha - 25dam2 = 100 dam2 - 25 dam2 = 75 dam2
7 dm2 + 42 mm2 = 10000 mm2 + 42 mm2 = 10042 mm2
4ha - 25dam2 = 375dam2
7dm2 + 42 mm2 = 70042 mm2
