Find the two numbers on either side of the given number and then work out the difference between the given number and the two "half" numbers. The smaller difference is the one which refers to the nearest half.
For example:
Suppose you are given 3.78
The numbers, in halves are ... , 3.0, 3.5, 4.0, 4.5, ...
Of these 3.5 and 4.0 are the ones which would be next to 3.78
Then 3.78 - 3.5 = 0.28
and 4.0 - 3.78 = 0.22
Since the second number is smaller, the nearest half is 4.0

What are the smallest and biggest whole numbers that round to 170000 to nearest 10000?
When rounding to the nearest whatever, half the number round up and half round down. → the numbers that round to 170000 to the nearest 10000 are 170000 ± (10000 ÷ 2) = 170000 ± 5000 However, if a number is exactly half way, the convention is to round them up, so the numbers in the range: 170000 - 5000 ≤ number < 170000 + 5000 → 165000 ≤ number < 175000 will round to 170000 to the nearest 10000 → smallest number is 165000 → biggest [whole] number is 175000 - 1 = 174999
What numbers can be rounded to the nearest ten to make 800?
Half of 10 is 5.So numbers in the range 800 ± 5 round to 800 to the nearest 10, except that numbers exactly half way round up. Thus all numbers greater than or equal to 800 - 5 round up to 800 and all numbers less than 800 + 5 round down to 800,That is all numbers greater than or equal to 795 and less than 805 will round to 800 to the nearest 10.
Why does it make sense to round a mixed number to the nearest whole number when estimating a sum or difference Could you round to the nearest one half instead?
Some people find it easier to add or subtract whole numbers but yes, you could round to the nearest half.

How do you round 4.5 to the nearest half?
4.5 already is rounded to the nearest half.

What is the biggest number that rounds to 8000 to the nearest thousand?
When rounding to the nearest thousand, half round up and half round down.Half of 1000 is 500 → numbers that are 8000 ± 500, that is 7500 to 8500 will round to 8000 to the nearest 1000.However, numbers half way by convention round up and 8500 is half way between 8000 & 9000 and so would round up to 9000.Thus numbers greater than or equal to 7500 and less than 8500 will round to 8000 to the nearest 1000.Therefore the largest whole number that will round to 8000 to the nearest 1000 is 8499.
What numbers would round to 520000 if rounded to the nearest ten thousand?
When rounding to the nearest ten thousand half round up and half round down. Thus 10,000 ÷ 2 = 5,000 numbers either side of 520,000 round to it, ie 520,000 ± 5,000. However, as numbers exactly halfway round up: Thus any number greater than or equal to 515,000 and less than 525,000 round to 520,000 to the nearest ten thousand.
What is the largest 5-digit number which rounds to 27 000 to the nearest thousand?
When rounding to the nearest thousand (1000), half the numbers (1000 ÷ 2 = 500) round up, and the other half round down - except for those which are exactly half-way: they round up. Thus the largest number that will round to 27,000 to the nearest thousand must round down to it and is 27,000 + 500 - 1 = 27,499.

How many numbers round to 350 to the nearest hundred?
There aren't any numbers that round to 350 to the nearest hundred.
How do round a fraction to the nearest half?
if the number after the first number after the decimal is 1-4, round it to 0. If it is 5-9, round it one higher number. EX: 4.56 rounds to 5.00, and 4.54 rounds to 4.50. They mostly round up to the nearest half number (like you said). It's not that hard to round numbers.
