• what is 10,000 rounded to the nerest 10,000?
• that would be 10,000
• what if you had to round 2999 to the nearest hundred
• If you underline the first 9, the second 9 tells you to round up, so rounding up to a 10 means 20+10 = 30, so 3000. Or if you round up the 9 to a 0, you have to add one to the next digit (2+1).
• why does 5 round up i think it us supposed do round down
• The reason 5 rounds up is because 0, 1, 2, 3, and 4 are part of the "lower half" which round down and the next greater place value is not influenced. 5, 6, 7, 8, and 9 are part of the "upper half" which round up and the next greater place value is increased by 1.

• What you do is you underline the tenthousand and then you circle the thousand 5 or above make the tenthousand one number higher and turn everything after that zero if it id 4 or below leave it alone and turn it all after the thousand zero. oh wait that question is from 9 years ago... -_-
• hello i am on a New account in khan academy and i am doing 4th grade courses. But i have trouble rounding to the nearest ten thosaund and hundred thousand. Can you please help me
• When rounding for any place value, you usually just take a look at if the value in the lower place value right below it is 0, 1, 2, 3, or 4 (0 to 4) or 5, 6, 7, 8, or 9 (5 to 9).
If the value is 0 to 4, you round down (the number of the place value you are rounding to stays the same).
If the value is 5 to 9, you round up (the number of the place value you are rounding to is increased by 1).
As I said before, this method is applicable for any place value, no matter how high you go (e.g. if rounding to the nearest one hundred million, you check what value is in the 99 million, and use that to determine whether you should round up or down).
• wait so if your gona round like 10000 and it was a number like 453243 would you still keep the 100 thousan in the number like 240000?
• This is kind of easy and hard you know what i'm saying
• I know so weired
• If Sal asks us "Round 550 to the nearest hundred". How will we do that ? I had a lot of confusion because 5 can either go down or go up
