30dm = 300cm = 3m. They're the same.
30 cm is equal to 3 dm. To convert from centimeters to decimeters, divide by 10 since there are 10 centimeters in one decimeter.
Yes.
30 centimeters is equal to 3 decimeters
They are both equal
3 decimetres is equal to 30centimetres.
Neither, 3 dm equal 30 cm. 10 cm = 1 dm → 3 dm = 3 x 10 cm = 30 cm
3 m : 20 dm =
That is correct. 3000 cm is NOT 3 m
Since 1 m = 10 dm, then 1 m 60 dm + 30 dm = 70 dm + 30 dm = 100 dm = 10m or 1 m 60 dm + 30 dm = 1m 90dm = 10 m.
m + m + m
They are equal. 1m = 100cm 3m = 300cm
