A dm (decimetre) is equal to 10cm (centimetres). So the answer to the question is 4dm is exactly the same length as 40cm.

4dm (decimetres) is exactly the same length as 40cm (centimetres)

They're the same amount because 10cm= 1dm and 10x4=40 and 1x4=4 and 4dm= 40cm

4 dm is greater than 400mm

40cm

There are 10 centimetres in one decimetre. Therefore, 4 decimetres is equal to 4 x 10 = 40 centimetres. The two units are therefore the same.

Neither - they are the same measurement.

1 decimeter is 10cm, so 4 is 40cm, greater than for 4cm

4dm=400cm that's what i think but I'm not so sure.

40 centimetres is greater than 40 millimetres.Note, there are 10 millimetres to 1 centimetre.Therefore, 40 millimetres only measures 4 centimetres.

Remember the mnemonic device: "Kids Have Dogs But Dogs Cost Money" or Kilo, Hecto, Deca, Base, Deci, Centi, Milli" So based off our mnemonic device cm is already less than dm. So therefore, 4cm < 4dm.

500mm is 25% bigger than 40cm.
