    Percentage Help Needed

    Hey,

    I was wondering whether someone could explain to me how to calculate grade percentages. The degree is made up of three elements. These elements are worth 50%, 20% and 30% each

    For element 1 (which is worth 50%) I got:

    63%, 61%, 61%, 61%

    For element 2 (worth 20%) I got:

    65% and 64%

    For element 3 (worth 30%) I got:

    42%, 58%, 64% and 62%

    I need to obtain 50% in each element in order to pass my course. But I just cannot seem to figure out how to calculate whether I got above 50% in each element. I've been trying to calculate it myself, but I just cannot seem to figure it out
    I'd be really thankful for any help!!!

    so what you do is add all for element one which comes to 246
    and you do 246 x 100 /(400) = 61.5%
    element two gives you 129*100/ 200 = 64.5%
    for element 3 gives you 226x100/400 =56.5%

    Now easy all you do is this
    61.5/2 + 64.5x20/100 + 56.5 x 30/100 = 60.6% so you passed.
