No.
30dm = 300cm = 3m. They're the same.
450 cm
Greater - 5000 cm is ten times longer than 5 m.
8 km is longer then 8 m as 5 m then 5 mm
No, 5000 meters is equal to 5 kilometers. Since 1 kilometer is equal to 1000 meters, 5000 meters is not longer than 1 kilometer, it is actually 5 times the length of 1 kilometer.
1.05 is greater than 0.25, so 1.05 m is longer than 0.25 m.
5,000 centimetres are the equivalent to 50 metres - which is a lot longer than 5 metres.
It's way smaller! That is INCORRECT. 1 metre = ~3.28 feet Therefore 5 m = ~16.4 ft 5 yards = 15 ft So, 5 m is longer than 5 yards.
There are 100 metres in one hectometre. Therefore, 5 hectometres is equal to 5 x 100 = 500 metres. This is 100 metres longer than 400 metres.
.4 Kilometres because if you convert it to metres it is 400.
Well, isn't that a happy little question! Yes, 3 km is longer than 2900 m. You see, 1 km is equal to 1000 m, so 3 km would be 3000 m, which is indeed longer than 2900 m. Just a little math magic to brighten your day!
1000 m is 1 km
