Step-by-step explanation:

To round off each number, we need to consider the digit in the next smallest place value.

For the number 2.5694 thousandths, the digit in the next smallest place value is 6. Since 6 is greater than or equal to 5, we round up the last digit. Therefore, rounding off 2.5694 thousandths would be 2.57 thousandths.

For the number 12.45877 ten thousandths, the digit in the next smallest place value is 8. Again, 8 is greater than or equal to 5, so we round up the last digit. Hence, rounding off 12.45877 ten thousandths would be 12.459 ten thousandths.

For the number 0.78999 thousandths, the digit in the next smallest place value is 9. Once more, 9 is greater than or equal to 5, so we round up the last digit. Therefore, rounding off 0.78999 thousandths would be 0.79 thousandths.

Remember, when rounding off numbers, if the digit in the next smallest place value is 5 or greater, we round up the last digit. If it is less than 5, we keep the last digit as it is.
