To round a mixed number to the nearest whole number, look at the fraction part. If the fraction is less than 1/2, round down. If the fraction is greater than or equal to 1/2, round up.

How do you round each mixed number to the nearest half in your estimate?
When rounding to the nearest half, round the fraction to whichever half the fraction is closest to on the number line. If a fraction is equally close to two different halves, round the fraction up.
How do you round fractions to the nearest whole number?
To round to the nearest whole number, you need to know that if the numerator, which is the top number, is half of the denominator, which is the bottom number. Then you can decide if the numerator is more or less than half the denominator. If you can do that, you can decide whether to round up or down.
How do you round a fraction?
To round off a fraction, you first convert the fraction to a decimal. If the division ends in a repeating decimal, you can stop after a certain number of decimal places and round off. Rounding numbers results in an estimated or approximate value.
How do you round to the hundredths place?
To round a number to the nearest hundredth , look at the next place value to the right (the thousandths this time). Same deal: If it’s 4 or less, just remove all the digits to the right. If it’s 5 or greater, add 1 to the digit in the hundredths place, and then remove all the digits to the right.
What is roundoff example?
In rounding off numbers, the last figure kept should be increased by 1 if the first figure dropped is greater than 5. For example, if only two decimals are to be kept, then 6.4872 becomes 6.49. Similarly, 6.997 becomes 7.00.

How do you round decimals to the nearest half?
We have to round six and one-tenth to the nearest half. Five-tenths are equal to a half. Is six and one-tenth closer to six and a half or six? Six is the same as saying six and no halves.
How do you round a fraction to the nearest tenth?
To round the decimal number to its nearest tenth, look at the hundredth number. If that number is greater than 5, add 1 to the tenth value. If it is less than 5, leave the tenth place value as it is, and remove all the numbers present after the tenth’s place.
How do you round a fraction to the nearest half or whole number?
When rounding to the nearest half, round the fraction to whichever half the fraction is closest to on the number line. If a fraction is equally close to two different halves, round the fraction up.
How do you turn a mixed fraction into a whole number?
Simply calculate the division represented by the fraction: 12 ÷ 4 = 3, and you’re left with a whole number instead of the fraction 12/4. Because the mixed number 2 and 12/4 means 2 + 12/4, you can rewrite the mixed number as 2 + 3 (substituting 3 for the fraction 12/4) and simplify that to 5 as the final answer.
How do I turn a fraction into a whole number?

How do you round to 0.5 in Matlab?
Y = round( X ) rounds each element of X to the nearest integer. In the case of a tie, where an element has a fractional part of exactly 0.5 , the round function rounds away from zero to the integer with larger magnitude. Y = round( X , N ) rounds to N digits: N > 0 : round to N digits to the right of the decimal point.
