Change the unit
50dm = blank cm
4,600 m = blank km
To change the unit from decimeters (dm) to centimeters (cm), you need to remember that there are 10 centimeters in 1 decimeter.
So, to convert 50 dm to cm, you multiply 50 by 10:
50 dm = 50 x 10 cm = 500 cm
Therefore, 50dm is equal to 500cm.
Now, let's convert 4,600m to km. Remember that there are 1,000 meters in 1 kilometer.
To convert 4,600m to km, you need to divide 4,600 by 1,000:
4,600m = 4,600 / 1,000 km = 4.6 km
Therefore, 4,600m is equal to 4.6km.
