The answer is the second option: Two places left.

Therefore, the complete text is: "To obtain the number of centimeters from a distance measured in meters, move the decimal point Two places left ".

The explanation is:

1 meter has 100 centimeters, then, if you have a distance of 45.55 centimeters and you want to know this value in meters, you need to divide it by 100 or, in others words, you need to move the decimal point two places left:

=(45.55 centimeters)(1 meter/100 centimeters)
=(45.55x1)/100
=0.4555 meters
