nhớ tíc cho minh nha

d)1,23m=12,3 dm
e)43,5m2=43 m2 50 dm2

f)8 ha 5 dam2=8,05 ha

f)8 ha 5 dam2=8,05 ha

a) 1 m² = 100 dm²

5 m² = 500 dm²

500 dm² =5 m²

b) 1 m² 50 dm² = 150 dm²

4 m² 20 dm² = 420 dm²

3 m² 9 dm² = 309 dm²

4m² = 40dm²

1/5m²  = 20dm²

2m² 25 dm² = 225 dm² 

^{tilk nha mèo con} 

\(4m^2=400dm^2\)

^{\(\frac{1}{5}m^2=20dm^2\)}

\(2m^225dm^2=225dm^2\)

k nha ^^

4 m² = 400 dm²

1/5 m² = 20 dm²

2 m² 25 dm² = 225 dm²

= 12,88 m2

= 2,7066 m2

= 400,98 dm2?

= 0,0955 dm2

\(\dfrac{7}{4}m^2=175dm^2\)

bằng 175 dm²

7/4 m²= 175 dm²

\(\dfrac{1}{4}m^2=0,25m^2\)

\(0,25m^2=25dm^2\)

25 dm²

4m²   20cm²= 4,0020 dm²

MIK BÍT

4 m² 20 cm² = 400,2 dm²
