Rounding is making an approximation of a number so it is easier to work with.
eg 1
9 ≈ 10 (≈ means approximately equal to)
53 ≈ 50
These two examples were rounded to the nearest whole number of 10.
eg 2
165 ≈ 200
545 ≈ 500
989 ≈ 1000
1378 ≈ 1400
These four examples where rounded to the nearest whole number of 100.
Since 25 is a whole number, the answer is 25.
To round to the nearest number.
The answer might depend on what you mean by "tn hundred".
Only if you were asked to find the mean to the nearest tenth. If so, don't round each number; calculate the mean first and then round it to the nearest tenth.
100
Since 25 is a whole number, the answer is 25.
To round to the nearest number.
I am not quite sure what you mean by the "lowest hundred" (or lowest hunderd, even). To the nearest hundred, it would be 549.99... recurring.
The answer might depend on what you mean by "tn hundred".
When you round something you take the number to the nearest whole. For instance 140 rounded to the nearest hundred (the place value) will be 100 while 160 would become 200
Improved Answer:- If you mean: 349,767 then it is 349,800
Round the number to the nearest tenth.
It's already there.
Only if you were asked to find the mean to the nearest tenth. If so, don't round each number; calculate the mean first and then round it to the nearest tenth.
I assume you mean to round it to the nearest whole number. In this case, you would round it up to 34
Well, isn't that a happy little question! To round 987 to the nearest whole number, we look at the digit to the right of the decimal point, which is 7. Since 7 is 5 or greater, we round the 9 up to 10. So, 987 rounded to the nearest whole number is 990. Just remember, there are no mistakes, just happy little accidents in math!
You mean nearest hundred? Ok, take the "hundred's" term (the third number to the left of the decimal) and look one to the right of the number. if the number on the write is greater than 4, add 1 to the "hundred's" number, write everything else as 0, remove everything after decimals. If the number to the right is SMALLER than 4, then leave the "hundred's" number as it is, do the same for erasing. I this case, the "hundred's" term is 2, the on to it's right is 6 > 4 so you round it to 300
