It refers rounding to the nearest integer or to zero decimal places.
The depends to what decimal place you are rounding the number.If you are rounding to hundredths, it will be 2.27If you are rounding to tenths, it will be 2.3If you are rounding to the nearest whole number, it will be 2.
To change a decimal into a whole number, you can either round it to the nearest whole number or truncate it by removing the decimal portion. For rounding, look at the digit in the first decimal place: if it's 5 or higher, round up; if it's 4 or lower, round down. Alternatively, if you simply want the whole number part without rounding, you can discard the decimal part.
5.75 rounded to the nearest whole number is 6. If rounding to one decimal place, it remains 5.8. If rounding to two decimal places, it stays as 5.75.
2.268 rounded to the nearest whole number is 2. If rounding to one decimal place, it becomes 2.3. Rounding to two decimal places keeps it at 2.27.
0.93 rounded to the nearest whole number is 1. If rounding to one decimal place, it remains 0.9. If rounding to two decimal places, it stays as 0.93.
18.998 rounded to the nearest whole number is 19. If rounding to one decimal place, it would be 19.0. If rounding to two decimal places, it remains 18.99.
37.096 rounded off to the nearest whole number is 37. If rounding to one decimal place, it becomes 37.1. When rounding to two decimal places, it is 37.10.
The estimate of 18.0573 can be rounded to 18.1 if rounding to one decimal place or to 18 if rounding to the nearest whole number. The context of the estimation will dictate which rounding method is more appropriate. Generally, for quick calculations, rounding to the nearest whole number is common.
You may be thinking of rounding (right of the decimal) or zero suppression (left of the decimal).
Rounding is important when dividing a decimal by a whole number to ensure the accuracy and precision of the final answer. When dividing, the quotient may result in a repeating or terminating decimal, and rounding helps to simplify the answer to a manageable and meaningful value. Rounding also helps to maintain the appropriate level of significant figures in the final result, which is crucial for maintaining the integrity of the calculation.
5.000 rounded to the nearest whole number is 5. If rounding to one decimal place, it remains 5.0. The number does not change when rounding to two or three decimal places either, as it is already expressed in that format.
It is rounded to 2.5 or 3 to the nearest whole number.
