a) 11.5%
b) 11.6%
c) 11.4%
d) 12.0%

Answer 1

The number 0.115 when converted to a percentage is 11.5%. Rounded to the nearest tenth, 11.5% does not change, remaining 11.5%, so the correct answer is option (a).

Step-by-step explanation:

To convert a decimal to a percentage, you multiply the decimal by 100 and add the percentage symbol (%). To convert 0.115 to a percentage, we perform the following calculation: 0.115 × 100 = 11.5%. However, the question asks for the percentage rounded to the nearest tenth. The digit in the hundredths place is a 5, thus, when rounding to the nearest tenth, 11.5% does not change because a 5 is followed by 0 (no digit) in this case.

So the correct rounded percentage is still 11.5% which matches option (a).
