4 of 10
40mm=______cm.
- A 4
- B 500
- C 5000
- D 50000
That's Correct!
It's Wrong!
The metric system uses a base of 10 for conversions between units. The prefix "milli-" means one thousandth, while "centi-" means one hundredth. Since a centimeter is ten times larger than a millimeter, to convert from millimeters to centimeters, you divide by 10. Therefore, 40 millimeters divided by 10 equals 4 centimeters.
