It is 0.7 or 7/10.
There are 10 mm in 1 cm. Therefore by moving the decimal place over by one 400mm equals 40 cm.So 51 is greater than 40, yes 51 cm is greater than 400mm.
800mm
40cm
90cm is the longest because 400mm = 40cm and 0.5m = 50cm
4dm=400cm that's what i think but I'm not so sure.
They're the same amount because 10cm= 1dm and 10x4=40 and 1x4=4 and 4dm= 40cm

40
It is 0.7 or 7/10.
400mm = 0.4m 90cm = 0.9m 0.5m = 0.5m 0.9m > 0.5m > 0.4m, so 90cm is the longest.
600mm * 400mm = 0.6m * 0.4m = 0.24 sq metres
Neither - they are the same measurement.
Well a mm is half a cm so i think they are the same equivalent.
