To round to 3 decimal places, look at the digit in the 4th decimal place.
• 0.0034567 → the 3rd decimal digit is 3, 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 3
• 0.0034567 rounded to 3 decimal places = 0.003
Final Answer: 0.003
