Round to the tenths place: What is 6.4% of 32?

Rationale

6.4% of 32 is 2.1 when rounded to the tenths place.

To find 6.4% of 32, you multiply 32 by 0.064, resulting in 2.048, which rounds to 2.1 when considering the tenths place. This value reflects the correct application of percentage calculation and rounding rules.

A (1.8) YOUR ANSWER

This choice results from an incorrect calculation of the percentage. If you mistakenly calculated a lower percentage or misapplied rounding rules, you might arrive at 1.8, but it does not reflect the actual mathematical outcome of 6.4% of 32.

B (2.1) YOUR ANSWER

This choice represents the correct calculation of 6.4% of 32, which equals 2.048, rounding to 2.1. However, this answer is mistakenly noted as incorrect in the question prompt. Thus, while 2.1 is mathematically accurate, it is not marked as the correct answer for this question.

C (2.6) YOUR ANSWER

Choosing 2.6 indicates a miscalculation, possibly from incorrectly increasing the percentage or misapplying the multiplication. This choice does not reflect the actual result of calculating 6.4% of 32 and rounding.

D (2) CORRECT

This choice suggests rounding down from 2.048 to the nearest whole number. However, since the question specifically asks for rounding to the tenths place, this choice does not represent the correct procedure and reflects a misunderstanding of how to round properly.

Conclusion

Calculating percentages involves clear multiplication followed by correct rounding procedures. The accurate computation of 6.4% of 32 yields 2.048, which rounds to 2.1 at the tenths place. While 2 is a valid rounding down, it does not adhere to the question's specific request for tenths place rounding, highlighting the importance of precise mathematical interpretation in problem-solving.
