1. The problem asks us to round the number 10.619. 2. Rounding means shortening the number to fewer decimal places or to the nearest whole number depending on the requirement. 3. If rounding to the nearest whole number, look at the first decimal place, which is 6. 4. Since 6 is greater than or equal to 5, we round the whole part (10) up by 1. 5. Therefore, 10.619 rounded to the nearest whole number is 11. 6. If you want to round to 1 decimal place, look at the second decimal digit, which is 1. 7. Since 1 is less than 5, the first decimal digit (6) remains unchanged. 8. Thus, 10.619 rounded to 1 decimal place is 10.6. 9. To round to 2 decimal places, look at the third decimal digit, which is 9. 10. Since 9 is greater or equal to 5, the second decimal digit (1) rounds up to 2. 11. Hence, 10.619 rounded to 2 decimal places is 10.62.
