What is 625.73548 rounded to the nearest thousandth?

625.735
625.740
626.000
625.730

The correct answer is: 625.735

To round the number 625.73548 to the nearest thousandth, we look at the digit in the thousandths place and the digit immediately to its right. In this number, the thousandths place is occupied by a 5 (in the position 625.735**5**48). The number immediately following it is 4. According to rounding rules, if the digit to the right of the place we are rounding to (in this case, the digit in the ten-thousandths place, which is 4) is less than 5, we leave the digit in the thousandths place unchanged. Thus, the 5 in the thousandths position remains 5. As a result, when rounding 625.73548 to the nearest thousandth, the answer is 625.735. This reflects proper rounding principles, ensuring that the value is accurate to the specified place without being misrepresented as it is more significant than it should be.
