Quizplus · Accepted Answer

The other answer choices either have too many or too few digits after the decimal point to match the requirement of approximating to three decimal places. Therefore, only choice D, 0.042, is the best option. The other answer choices are clearly not possible based on the given number of digits in the answer. Choice A only has three digits after the decimal point, but we need at least four to approximate to three decimal places. Choice B has too many digits before the decimal point, and choice C has a decimal point but not enough digits after it. Therefore, our best choice is D.
