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.
2 km = 20,000 dm
515 km = 515 x 10 dm = 5,150 dm
there are 200 cm in 20 dm
Assuming decimeters.... 0.0001 km Algebraic Steps / Dimensional Analysis 1 dm*1 km 10000 dm=0.0001 km
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.
Answer: 6540 dm = 0.654 km
2 km = 20,000 dm
No.
By unit of length and distance and conversion ,we can say that 1 km =10000 dm 56 dm =0.0056 km
10
Assuming decimeters.... 0.0001 km Algebraic Steps / Dimensional Analysis 1 dm*1 km 10000 dm=0.0001 km
dm = 10**-1m km = 10**3m 10000dm / km 324*100=3240000
200 dm
The conversion between dm and km are given .On finding the relation we get as follows . we know ,1 km=10000 dm.
By unit of length and distance and conversion ,we can say that 1 km =10000 dm 100 dm =0.01 km
10 cm = 1 dm 20 cm = 2 dm
