SUMMARY
The correct method for rounding the number 3.549 to two significant figures is to focus on the digit in the one-tenths place, which is 5. According to standard rounding rules, since the digit to the right (the one-hundredths place) is 4, the one-tenths digit remains unchanged. Therefore, the rounded result is 3.5, not 3.6. This approach emphasizes the importance of identifying significant figures correctly in numerical rounding.
