They're the same amount because 10cm= 1dm and 10x4=40 and 1x4=4 and 4dm= 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.
4dm=400cm that's what i think but I'm not so sure.
500mm is 25% bigger than 40cm.
They're the same amount because 10cm= 1dm and 10x4=40 and 1x4=4 and 4dm= 40cm
4 dm is greater than 400mm
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.
40cm
Neither - they are the same measurement.
1 decimeter is 10cm, so 4 is 40cm, greater than for 4cm
40 centimetres is greater than 40 millimetres.Note, there are 10 millimetres to 1 centimetre.Therefore, 40 millimetres only measures 4 centimetres.
4dm=400cm that's what i think but I'm not so sure.
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.
6.4m is larger. 6.4m is the same as 6m 40cm. 6.04m would be 6m 4cm, which is smaller than 6.4m.
6.4 metres as .4 means 40cm
