Question

How do you change 0.452 into a percent and how do you round it to the nearest tenth of a percent?

Answer 1

Hint: In the given question, we have been asked to convert a decimal number into a percent. Then, after converting it to a percent, we have to round it off to the nearest tenth. To round it off to the nearest tenth, the number in the hundredth place is going to determine the outcome.

Complete step-by-step answer:
The given decimal number is \[0.452\].
For converting any decimal to percent, we just multiply the decimal by \[100\].
Hence, \[0.452 = \left( {0.452 \times 100} \right)\% = 45.2\% \]
Now, to round the percent off to the nearest tenth, we are going to look at the number in the hundredth place as it is going to determine the outcome. But, there is no number in that place, so there is going to be no rounding off and hence, the answer is \[45.2\% \].

Note: As we saw in this question that if a thing has been given to solve, we do not solve it if its condition is not present in the answer. Like in the question, we had to round the percent to the nearest tenth, and to do that, we needed to check the digit at the hundredth’s, but since there were no hundredth’s in the first place, no rounding off happened.
