What are the steps for rounding a Decimal number? 1) First, determine the value to which you are rounding. 2) Look to the ________ (left or right) of that number. 3) If the number is ________ (less or greater) than 5, the number to which you are rounding stays the same. 4) If the number is ________ (less or greater) than or equal to 5, add ____ (which number?) to the number to which you are rounding.

1) First, determine the value to which you are rounding. 2) Look to the right of that number. 3) If the number is less than 5, the number to which you are rounding stays the same. 4) If the number is greater than or equal to 5, add 1 to the number to which you are rounding.
