What are Whole Numbers?
The restaurant dinner bill for your family reunion is a whopping $1,954.00! I hope you have enough money to pay so that you don't have to go back into the kitchen and do the dishes! Your dad wants to figure out a great tip for the helpful and hardworking waiters. Therefore, he rounds the bill total to the nearest thousand, making it an even $2,000. Now it's easy for him to take 20% of $2,000 (making the tip $400 for the waiters). Can you see why rounding whole numbers is helpful in real life?
Before you learn to round whole numbers, you may want to review the definition of a whole number. A whole number is any number that doesn't have a decimal or fraction. Yes, it's really that simple! Here are some examples of whole numbers:
1
2
47
159
256,406,264
No matter how big the number, it is still considered a whole number if it does not have decimals or fractions. Now, let's do a quick number line review.
Plotting a Number on a Number Line
A number line is a line on which numbers are placed in intervals, to show basic numerical calculations. Plotting a number on a number line means that you are marking a point designating that number on the number line. Using a basic number line that illustrates numbers 1-10, we would plot the number 4 as shown:
Number line with plot of 4
Rounding Using a Number Line
OK. Now let's take our number line knowledge and use that to round whole numbers. Look at our number line from the above example. If you were asked to round the number 6 to the nearest 10, what would you get and where would you plot it? Well, the nearest 10 is going to be a multiple of 10. What are the multiples of 10 that are on opposite ends of the 6? 0 and 10. But is the 6 closer to the 0 or 10? The 10 of course! Therefore, if you were to round 6 to the nearest 10, your answer would be 10 and that is where you would plot it!
Rounding to the Nearest Hundred
Rounding whole numbers can get a little more complicated when the number is larger. But once you get the hang of it, it will be easy! Let's round 357,468 to the nearest hundred.
Step 1 - Find Correct Place Value
Determine which digit is in the hundreds place. It's the 4 because it is the third number from the right and it tells us how many hundreds are in a number.

Place value 2
Step 2 - Create Number Line and Plot
Draw a number line with whole numbers as this creates a visual to help you solve the problem. Very important: Because you are rounding to the nearest hundred, your intervals on the number line should go by hundreds. This number line represents the multiples of hundred on either end of 357,468. When we plot the approximate location of 357,468 on the number line (this is the red dot), we can see the nearest hundred. The nearest hundred of 357,468 is 357,500

Step-by-step explanation:
If the rounding number is 5 or more it is rounded up. 35, 36, 37, 38 and 39 round up to 40. To round a number to thenearest ten, the digit in ones place is considered. If > = 5, rounded up and if < 5 rounded down.When rounding to the nearest hundred, look at the TENS DIGIT of the number.
If that digit is 0, 1, 2, 3, or 4, you will round down to the previous hundred.
If that digit is 5, 6, 7, 8, or 9, you will round up to the next hundred.
What is 34519 rounded to the nearest thousands? 34519 rounded off to thenearest thousandth is 35000. In 34519, the hundredth digit is 5 and so, roundingoff 34519 to the nearest 1000 result in 35000.
