Yes, i know, I am really bad at maths...but I have to work out this persentage....if someone could just show me how...
i've got to give art students marks, but presentation alone works out 40% of the final mark. How do I work this out?
in other words the first mark should count 40% of the final mark and the second mark should count 60% of the final mark?
help?

work it out as 100%. forget about the 40% n the 60%. use an average

Well assuming you had a brilliant student who scored full marks the split between presentation and other work would be as you said.Now if it is predetermined what the final perfect mark might be, 100,60,400,or whatever split this figure into a 60/40 ratio. If the total was 100 you would mark your pupil out of 40 for presentation and 60 for the rest. Suppose you marked them 25 for presentation and 40 for other work this will still maintain the 60/40 split of their final total of 65. Again if the total perfect mark was 60 you would mark out of 24 for pr and 36 for other.and so on.

Why not mark presentation out of 40, and the other aspects out of a total of 60. Then add the two marks together, to get an overall total out of 100. Which is what percentage means.

Well, you need to know what the total mark would be if they achieved a flawless 100%, then ratio it 40/60 ie. If the total possible mark was 50, then 40% of it would apply to the presentation, which would be a maximum of 20 points - and 30 points would be allocated to rest of the exam.

Multiply the mark that's supposed to be 40% by 40/100 or 0.4
For example, if they got the mark 68, then multiply 68 x 0.4 to make it worth 40% of the total.
Same thing with 60% multiply that mark by 60/100 or 0.6.
Then add the two together for a total of 100% (as you can see, 0.4 + 0.6 equals 1.0 which is 100%).
You can do this with any kind of percentages, so long as when they're added together they total 100%.
For example, if you had a course with one part worth 10%, another worth 20%, another worth 30% and the last one worth 40%, you could multiply each one by it's 0.1, 0.2, 0.3 and 0.4 and then add them up together.
I hope that helps.

40% is simply 40 divided by 100 multiplied by the number you are trying to get a percentage of.

METHOD 1
Mark the first part out of 40
Mark the second part out of 60
Add the two marks together for a total mark out of 100
METHOD 2
Mark 1st out of 100 (M1)
Mark 2nd out of 100 (M2)
Final mark = (M1 x 0.40) + (M2 x 0.60)
Gives a final mark out of 100
Many other methods

let: x1 be the first mark and x2 be the second mark
so, x1 * 0.4 and x2 * 0.6 would equal to 100% if given perfect marks.
for example, someone got grades of 98 and 80 respectively.
x1 = 98 and x2 = 80,
then his final grade would be {(98*0.4)+(80*0.6)} = 87.2
