2 dm = 200 mm
greater than
10 dm = 1 m so 200 dm = 20m. 20 km is 1000 times as long. This is assuming "dm" = decimetres. If it = dekametres then 200 would be 2 km.
By unit of length and distance and conversion ,we can say that 1 km=10000 dm 20 km =200000 dm It is greater than 200 dm.
20 cm 1 cm = 10 mm 1 mm = 0.1 cm
mm means "millimeters"dm means "decimeters"Note that "milli-" means "thousandths of a unit" and "deci-" means "tenths of a unit".This means:1 m = 1000 mm1 m = 10 dmCombine these conversions altogether to get:1 mm = 1.0 x 10-3 m = 1.0 x 10-2 dmAnother way of interpreting this is 1 dm = 100 mm. Therefore, 200 mm is 2 dm.
Putting them in a common unit is a great start. 200 mm is equal to 0.2 m, 22 dm is equal to 2.2 m and 22 cm is equal to 0.22 m. Therefore, the order from least to greatest is 200 mm, 22 cm, 2 m and 22 dm.
No. 1 meter = 100 cm = 1000 mm accordingly, 2 meters = 2000 mm and 200 mm = 0.2 meter
2 m is 200 cm 0r 2000 mm 200 cm. 2000mm
By unit of length and distance and conversion ,we can say that 1 dm =10 cm 2 dm=20 cm hence ,2 dm >18 cm
1 dm = 10 cmAv. doorway = about 2m2m = 20 dm
24 meters is 2400 cm. You can take it from there.
