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.
If the fraction is less than half, round down. If the fraction is half or greater, round up.
You look at the fraction part (0.302) and see that it is less than one half, so you round it down to 2.
4.5 already is rounded to the nearest half.
4/5 to the nearest half is 1.
It is 2.5
If the fraction is less than half, round down. If the fraction is half or greater, round up.
To round a fraction to the nearest half, first convert the fraction to a decimal. Then round the decimal to the nearest half by determining which half interval it is closest to. Finally, convert the rounded decimal back to a fraction if needed.
You look at the fraction part (0.302) and see that it is less than one half, so you round it down to 2.
4.5 already is rounded to the nearest half.
To the nearest half, one half
1,500,000 is already rounded to the nearest half-million.
4/5 to the nearest half is 1.
Well, honey, when you're dealing with fractions, one third doesn't round to 0 or one half. One third is closer to zero than it is to one half, but it's still one third. So, no need to round it off, just keep it as one third and call it a day.
