Express 30cm as a decimal of 2km.
We can start by converting both measurements to the same unit, either centimeters or kilometers.
30 cm can be converted to kilometers by dividing by 100, since there are 100 centimeters in a meter and 1000 meters in a kilometer:
30 cm ÷ 100 = 0.3 meters
0.3 meters ÷ 1000 = 0.0003 kilometers
Therefore, 30 cm is equal to 0.0003 km.
To express this as a decimal of 2 km, we can divide 0.0003 by 2:
0.0003 ÷ 2 = 0.00015
Therefore, 30 cm is 0.00015 of 2 km, or 0.015%.
To express 30cm as a decimal of 2km, we need to convert both the centimeters and kilometers into the same unit, such as meters.
1 kilometer (km) = 1000 meters (m)
So, 2 km = 2 x 1000 m = 2000 m
1 meter (m) = 100 centimeters (cm)
So, 30 cm = 30 / 100 m = 0.3 m
Now, we can express 30 cm as a decimal of 2 km:
0.3 m / 2000 m = 0.00015
Therefore, 30 cm is equal to 0.00015 decimal of 2 km.
