3. To change megameters to meter, how do you move the decimal?

Answer 1

when you are going from bigger things to smaller things, move the decimal point to the right; when you are going from smaller things to bigger thins, move the decimal point to the left.  There are going to be a whole lot more centimeters in a meter so it will be a bigger number. so technically 39.0 meters would be 390.0 centimeters, etc
