    Maths issue, 1-SUM

    Easy one for the educated

    How does 6% get to 6.38% on the attached, I don't know what 1-SUM does to the calculation.

    Can someone explain it in a really dumb way how one figure gets to the other.

    Re: Maths issue, 1-SUM

    Sum(b3:b4) = 6%

    1 = 100%

    1-sum(b3:b4) = 100% - 6% = 94%

    b3 / sum(b3:b4) = 3% / 94% = 3.191%

    3.191% + 3.191% = 6.38%

    How old are you?
    Not an insult, just curious as I thought most people would know this.

    Ensure you describe your problem clearly, I have little time available to solve these problems and do not appreciate numerous changes to them.
