You do not! You round up OR DOWN, depending on the context.

Suppose a bunch of people want to go to a show and tickets cost 25 dollars and suppose there 120 dollars.

120/25 = 4.8 tickets. But only 4 people can go to the show. Not 5 - not unless you get hold of another 5 dollars.

How do you round when a mixed number is halfway between two whole numbers?

I assume in your question you are asking what happens when a number is in between two whole numbers. E.G 4 and 5 the middle is 4.5 If you wanted to round this up to 1 significant figure or an integer/whole number the rule is that if in the middle you always round up to the highest number. In the case of the example the answer would be 5 if you were to round it up.


Why do we sometime round up or down numbers?

Sometimes you round up or round down numbers to get close to the correct answer so that you can make sure that your answer is right. If your answer is not close to the rounding down of the numbers you are using then you need to look it over and do it again.


How do you round to the nearest tenth and hundredth?

Always look at the next digit. If it's between 0 & 4 inclusive - round the number down. If it's between 5 & 9 inclusive - round up. Take the numbers 10.094 and 10.096. 10.094 would round down - to 10.09... 10.096 would round up to read 10.10


What is the biggest number you can round of 120000?

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.


How do you round numbers that end in 5?

up, so you would round 3.5 to 4.

Are UTs on HorseIsle whole numbers?

The percentage of the horse's UTs are very rarely whole numbers. If you are calculating the UTs of a horse, simply round up or round down (less than 5, you round down. 5 and up, you round up!). However, the actual UT stats (such as 670 out of 700 intelligence, just as an example) are always whole numbers.

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
