Q:
# Which reason best describes why you can divide any number by 100 by moving the decimal point two places to the left?Dividing a number by 100 is the same as subtracting the number 100 times.Dividing by 100 is the same as removing a zero.Moving the decimal point makes the number smaller.Moving the decimal point two places to the left makes the number 1/100 of its original value.

Accepted Solution

A:

The last choice is the reason, but to add to this, you are taking a value and breaking it into groups of 100( which is 10 groups of 10). Each place value in our decimal system naturally is based on a system of tens! Dividing by 100, is 2 groups of tens (2 decimal moves).
