To round to 3 decimal places, look at the digit in the 4th decimal place.
• 0.00849 → the 3rd decimal digit is 8, the 4th decimal digit is 4
• The 4th decimal digit is 4, which is less than 5, so we do not round up
• Keep the 3rd decimal digit as 8
• 0.00849 rounded to 3 decimal places = 0.008
Final Answer: 0.008
