Lesson 4: Rounding numbers

# Rounding whole numbers to nearest thousand

Sal rounds 423,275 to the  nearest thousand. Created by Sal Khan and Monterey Institute for Technology and Education.

## Want to join the conversation?

• I have a problem at rounding up this number, this is either my teacher teach me this or I just don't know:
``Round 14,699 to the nearest ten thousand``

I have 2 way of doing this
``- Round every single number, start at the one, and then move up to ten thousand.- Round the thousand.``

If with way 1, I'll get 20000 (my teacher taught me this)
If with way 2, I'll get 10000 (like the demonstration)

Which way is correct?
• The answer would be 10000. You always use the digit to the right of the place you want to round to help you determine whether to round up or down. But notice you said "round the thousand", but you are actually rounding the ten thousand, by looking at the thousand.
• when you round to the nearest hundred thousand what do you do?
• When you round to the nearest hundred thousand you round up by a hundred thousand. For example, lets say you have, 587,531, when you round to the nearest hundred thousand it becomes 600,000. Hope this helps.
• How do you round fraction
• 8/7you can round that to one because 7/7 is one,and 8/7 is not too much bigger. hope this helps
• I think he switched the greater than and less than sign.<5 >5
• The inequalities are correct. Sal initially made an error, but immediately corrects his error.
• Oh my goodness I am so confused someone help me!
Edit: Thank you for all the support now I finally get it!
• So, just try to get this formula -
When it is rounding of to tens, check the ones place.

When it is rounding of to hundreds, check the tens place.

When it is rounding of to thousands, check the hundreds place.

Got the pattern? So it is like we go to check the before digit. So if I ask you to round ten-thousands, the answer should be to check the thousand's place. So, now that we have to round to the thousand's, I am going to check the hundred's place.

Let's take the number 343,798 for example. Now, check the hundred's place. Did you get it? Well, the hundred's place is 7. So, is it 5 or more than 5, or less than 5? Well, it is 7 so it is greater than 5. So it will go forward. So it will become 10. Then the numbers which are front of it will also become 0. So, the number's 9 in the ten's digit and the number 8 in the one's digit will become 0. Now, is the rounding finished? No, it is not. The number 7 has become 10 so we have to change the thousand's digit, in this case, 3. Now, add 1 to 3, because the ten's place in the number 10 is 1. So after you add 1 to the thousand's place, it becomes four. And, we are done. The answer is 344,000. If you got it, please comment below and this a challenge, try to figure out what happens if the hundred's place is less then 5. Comment below! And please give the answer to this question. 254,667 rounded of to the nearest thousand's. Feel free to comment down below if you have any doubts. I am glad to answer!

• yeah 5 is supposed to round up. 5 is closer to the following.
• I have A problem with every thing about rounding. I
can under stand when it to small number like 59 or 188 I know 188 round to the nearest one is 190 so can you start easy so we can under stand better. I need help on nearest thousand ten thousand like 34789 what do I do when number like 34789 and they
don't have A neighbor like this number 34789 rounded be the nearest ten thousand? for Fope
Have you ever gone shopping with your parents and heard them say something costs about \$5, but the price tag says \$4.99? That's rounding! Rounding is like giving numbers a little nudge to make them easier to work with.

Imagine you have a bunch of marbles, and you want to put them into groups of 10 because it's easier to count by tens. But what if you have 37 marbles? You can't make four full groups, can you? So, you make three groups of 10, and you have 7 left over. In rounding, we decide whether to keep those 7 marbles as they are or add a few more to make another full group of 10.

Here's how we can decide:
• If the number is 5 or more, we give it a boost up to the next group of 10.

• If the number is less than 5, we just leave it as it is.

So, if we go back to our marbles, we have 7 left after making three groups of 10. Since 7 is more than 5, we can add 3 more marbles to make it 40. Now, we have four full groups of 10 marbles!

Let's try with a number like 52. The 5 in 52 tells us we already have five groups of 10, and the 2 is like having 2 extra marbles. Since 2 is less than 5, we don't add any more marbles. So, 52 stays as 50 when we round it.

Remember, rounding helps us with big numbers too! If you see a number like 164, you look at the 6 (which is in the tens place) and think about your marbles. Since 6 is more than 5, you add one more group of 10. So, 164 becomes 170 when we round it to the nearest ten.

Rounding is super useful when you're in a hurry or when exact numbers aren't that important. It's like making numbers neat and tidy for a quick look!

I hope this essay helps you understand rounding in a fun and simple way! If you need more examples or exercises, feel free to ask. Happy learning!
• The only way I could do that was if you had to do a little more more research and I could see if I can do that and then you can just go ahead with the other two things and I could just go to your place or whatever and I could go back and do that if if I want you you could do it and I can just do that but you can just go back and see if I have to go to work and I can do it and then I could do that but you could just do it if I you can just do it and I can go back and I do that I can do it and I can just go do that I just don’t know what you want me and to be honest with me to be able do it I just want you can go back and do that I can go back and do that I can just just go ahead with the the the the the other
