Round 297.85 square kilometer to the nearest tenth of a square kilometer?
297.8 square kilometres. Now here is a minor digression that you may (or may not) find is of interest: There are different views on how the digit 5 should be rounded - up or down. 1,2,3 and 4 are always rounded down; 6,7,8 and 9 are always rounded up and 0 does not need rounding. So if you always round 5 down, you will round down 5 numbers and up 4 and so introduce a downward bias in your work. Conversely, if you always round up you will introduce an upward bias. You could randomly decide to round up or down but this makes it more difficult for others to follow what you have done. The recommended answer is to round 5 so that the previous digit is EVEN. Thus 0.15 is rounded up to 0.2 and 0.45 is rounded down to 0.4

120005 Some people will argue that 5 should always be rounded up. That is wrong since it introduces an upward bias. If you follow these rules: 0 no rounding required. 1,2,3,4 round down 5,6,7,8,9 round up A random set of numbers will end equally in any one of the digits. You are round up 5 times out of ten and rounding donw only 4 out of ten. This introduces a bias. The solution is to round 5s up or down to an even digit. Then 1 out of ten does not require rounding, 4 out of ten are always rounded down, 4 out of ten always rounded up, and one is rounded up or down with equal probability. Result? Expected bias = 0.
