Trước khi làm bài, cho mik hỏi tí, viết dưới dạng phân số, hỗn số hay là số thập phân vậy bn, hay là mik viết tạm theo cả 3 kiểu như thế nha nhưng vẫn là 1 bài.

Đề bài: Viết các số đo sau dưới dạng số đo có đơn vị là mét vuông:

\(6m^235dm^2;8m^227dm^2;16m^29dm^2;26dm^2.\)

Trả lời:

\(6m^235dm^2=635dm^2=\frac{635}{100}m^2=6\frac{35}{100}m^2=6,35m^2.\)

\(8m^227dm^2=827dm^2=\frac{827}{100}m^2=8\frac{27}{100}m^2=8,27m^2.\)

\(16m^29dm^2=\frac{1609}{100}m^2=16\frac{9}{100}m^2=16,09m^2.\)

\(26dm^2=\frac{26}{100}m^2=0,26m^2.\)

Do cái cuối cùng là phân số có tử số nhỏ hơn mẫu số nên mik ko thể chuyển nó thành hỗn số đc, vì để chuyển một phân số sang hỗn số thì điều kiện bắt buộc phải có là: tử số của phân số đó phải lớn hơn mẫu số của phân số đó. Nhưng mik cũng đổi đc sang phân số và số thập phân.

Chúc bn học tốt.

a )   12 h a   =   120   000 m 2           5 k m 2   =   5   000   000 m 2     b )   2500 d m 2   =   25 m 2           90   000 d m 2   =   900 m 2 c )   8 m 2   26 d m 2 = 8 26 100 m 2         45 d m 2 = 45 100 m 2 d )   20 m 2   4 d m 2 = 20 4 100 m 2         7 m 2   7 d m 2 = 7 7 100 m 2

Viết các số đo sau dưới dạng số đo có đơn vị là đề_ xi_ mét vuông:

8m2 36dm2= 836 dm2

19m2 8dm2= 1908  dm2

Viết các số đo sau dưới dạng số đo có đơn vị là xăng_ ti_ mét vuông:

4dm2 45cm2= 445 cm2

14dm2 85cm2=  1485 cm2

105dm2 6cm2=...cm2

105 dm2  6cm2 = 10506 cm2

Ừ đúng rồi đấy 10 điểm

Vào câu trả lời tương tự sẽ có thôi

6 m 2   58 d m 2   =   6 m 2   + 58 100   m 2 =   6 58 100 m 2 19 m 2   7 d m 2   =   19 m 2   +   7 100 m 2   =   19 7 100 m 2

6m2 58dm2=6 58/100m2

19m2 7dm2=19 7/100m2

43dm2=43/100m2

Viết các số đo sau dưới dạng số đo có đơn vị là mét vuông

6m² 58dm²= 658 m²

19m² 7dm²= 1907 m²

43dm²= \(\frac{43}{100}\)m²

67 dam2 51m2 = 67 dam2 +  m2 =  dam2
82 dam2 7m2 = 82dam2 +  m2 =  dam2
