Rounding numbers coverts large numbers and decimal numbers to simpler forms which are then useful to solve or express in a given question. This concept is commonly used in many word problem and different calculations. A whole number is a non-decimal number, non-negative number starting from zero. While rounding to the nearest whole number if the number to the right of the rounding number is less the 5 round down and if the number is 5 or more round up. Then replace the removed digits by zeroes in the given number.

Example 1: What is 5,673,489 rounded to nearest thousand?
Solution: For rounding find the place to round, next look for the number right to the place. If the number is less the 5 round down and if the number is 5 or more round up.
The number in the thousand’s place is 3 in 5,673,489.
The number to the right of the thousand’s place 3 is 4 which is less than 5.
Replace all the numbers to the right of thousands by zero’s.
Hence rounding the number is 5,673,000.
