Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the second number. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
If one were to round the number 12.45 to another number, there are a couple of options. First, one can round the number to 12.5 or one can round the number to 13.
As the first digit after the decimal point is a 5, we round up to give 57 as the answer.
As the first digit after the decimal point is a seven, it will round up to give 35 as the answer.
As the first digit after the decimal place is a 4, the number is rounded down, giving 120 as the answer.
If I think your asking the question how I think your asking it, then any number 5 and above you round up. If its below 5 you round down. :-)

first you have to round it to the nearest 10 whichwill be 330 and then you have it :)
you should round it to the nearest tenth and box the first number
since the first number after the decimal is less than 5, round to 412
round up to 45.5 in the first stage then to 46 in last.
Look at the first number after the decimal; if less than five round down; if 5 or greater round up In your case answer is 4
If first digit of a number is 0-4, round down. If it is 5-9, round up.
to round to the nearest whole number you have to look at the first number and if it is greater than 4 round it up but if it is less than 4 round it down hope this helps
In the decimal system, the first number after a decimal is the tenth spot, then the hundredth, then the thousandth. Also, when you round, if a number is above five, then you round to the next number, if it is below five you stay with the number you have. In this case the answer would be 30.09.
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.
As the first digit after the decimal point is a 5, we round up to give 57 as the answer.
As the first digit after the decimal point is a 2, we round down to give 13 as the answer.
