Answer 2

To round to 3 significant digits, start counting from the first non-zero digit. If the digit to the right of the third significant digit is 5 or greater, round up. If the digit is less than 5, leave the third significant digit unchanged. Replace all digits to the right of the third significant digit with zeros.
