Well, isn't that a happy little question! To round 16.66 to the nearest whole number, we simply look at the decimal part. Since the decimal part is .66, which is more than halfway to 1, we round up to the next whole number. So, 16.66 rounded to the nearest integer is 17.
15.75 rounded to the nearest integer is 16
521 rounds to:1000 the nearest thousand500 to the nearest hundred520 to the nearest ten
Since 269 is an integer, it is already rounded to the nearest fractional part.
Since 36 is an integer, it is already rounded to the nearest tenth.
Since 14857 is an integer, it is already rounded to the nearest fractional part.
As 5 is immediately after the decimal point we round up, so the answer is 78.
5 is an integer and so already rounded to a tenth.
-39, itself, is the nearest integer.
That depends on what you are rounding to. 8.6 rounded to the nearest tenth (or less) is 8.6; to the nearest integer is 9; to the nearest multiple of 10 is 10; to the nearest multiple of 100 (or more) is 0.
Since 4437 is an integer, it is already rounded to the nearest fractional place.
As 200 is an integer, it is already rounded to the nearest fractional part. If you wish to indicate tenths in the answer, the number would be written 200.0.
This term is used in rounding. For example, if you are supposed to round 2.8 to the nearest integer, the answer is 3, because 2.8 is nearer to 3 than to any other integer. (2.8 is between 2 and 3; it is closer to 3 than to 2.)
