To round numbers to the greatest place value, you first identify the target place value you want to round to. Then, you look at the digit to the right of the target place value. If that digit is 5 or greater, you round up by adding 1 to the target place value. If the digit is less than 5, you leave the target place value as it is. Finally, replace all digits to the right of the target place value with zeros.
