50 dm2 = 5000 cm2 5m = 50 dm = 500 cm
4000 cm2 = 40 dm2 500000 cm2 = 5000 dm2 =50 m2
50dm2 = 5000cm2 5m = 50dm = 500cm
4000cm2 = 40dm2 500000cm2 = 5000dm2 = 50m2
1/4m2 = 25dm2 = 75cm2 25kg = 1/4 tạ
\(50dm^2=5000cm^2\) \(5m=50dm=500cm\)
\(4000cm^2=40dm^2\) \(500000cm^2=5000dm^2=50m^2\)
\(\frac{1}{4}m^2=25dm^2=2500cm^2\) \(\frac{4}{5}\)tấn\(=800kg\)
\(\frac{3}{4}dm^2=75cm^2\) \(25kg=\frac{1}{4}\)tạ
