To round numbers to specific place values, identify the digit at the place value to which you want to round. Then, look at the digit immediately to the right. If this digit is 5 or greater, round up; otherwise, round down. Apply this rule to each specified place value.
To round to the nearest ten thousands, identify the digit in the ten thousands place, which is 3 in 139,275.619. The digit to the right is 9. Since 9 is greater than 5, we round up. Thus, 139,275.619 rounded to the nearest ten thousands is 140,000.
For rounding to the nearest hundreds, the digit in the hundreds place is 2. The digit to the right is 7. Since 7 is greater than 5, we round up. Therefore, 139,275.619 rounded to the nearest hundreds is 139,300.
To round to the nearest tens, the digit in the tens place is 7. The digit to the right is 5. Since 5 is equal to 5, we round up. Thus, 139,275.619 rounded to the nearest tens is 139,280.
For rounding to the nearest hundredths, the digit in the hundredths place is 1. The digit to the right is 9. Since 9 is greater than 5, we round up. Therefore, 139,275.619 rounded to the nearest hundredths is 139,275.62.
To round to the nearest ten thousands, the digit in the ten thousands place is 2. The digit to the right is 9. Since 9 is greater than 5, we round up. Thus, 29,981.341 rounded to the nearest ten thousands is 30,000.
For rounding to the nearest hundreds, the digit in the hundreds place is 9. The digit to the right is 8. Since 8 is greater than 5, we round up. Therefore, 29,981.341 rounded to the nearest hundreds is 30,000.
To round to the nearest tens, the digit in the tens place is 8. The digit to the right is 1. Since 1 is less than 5, we round down. Thus, 29,981.341 rounded to the nearest tens is 29,980.
For rounding to the nearest hundredths, the digit in the hundredths place is 4. The digit to the right is 1. Since 1 is less than 5, we round down. Therefore, 29,981.341 rounded to the nearest hundredths is 29,981.34.
\(\boxed{140,000, 139,300, 139,280, 139,275.62, 30,000, 30,000, 29,980, 29,981.34}\)
