Quizplus · Accepted Answer

The rules of significant figures state that when adding or subtracting, the answer should have the same number of decimal places as the measurement with the fewest decimal places. In this case, all options have the same number of decimal places, so we need to consider the number of significant figures. The original number has 5 significant figures, therefore the answer should also have 5 significant figures. Choice A and C have only 2 significant figures, while choice B and E have 5 significant figures but their last digit is uncertain. Choice D has 5 significant figures and is the closest approximation to the original number given.
