What is 0.5 times 234.987 - Significant Figures?

  1. Feb 10, 2006 #1
    The question is 0.5 x 234.987

    And no the answer is not 117.4935

    i need to convert that number 117.4935 into one number. As 0.5 is only one significant figure.

    Huh? If you want to retain only one significant figure then keep the most significant digit and drop the rest. 117.4935 is closer to 100 than to 200, so using a single significant the answer is 100. Unless I misunderstand your question.

    What's the context of the question, Indigo? Significant figures are treated differently in different contexts. If you want to divide 234.987 by 2, you can keep a lot of the digits....
