HI,

I forgot this stuff and feel terrible and useless.

I need to find out what is the % value of each amount of units ..... that make up a pie.

so of the pie for example... i have a few items or categories....

So for each value below how to work out what they represent in the pie.
I forgot how the hell u do this:

15 000
75 000
90 000
200 000

do u say 15 000 / 100 ; and 75 000 / 100 ; and 90 000 / 100 ; and 200 000 / 100 ?
but then i dont know what the hell to do next.

I dont know how to search this on google or youtube even because i know what the hell u call it

Thanks

(Piece of pie / Total of all the pie) *100 = percentage for that piece.

Add up all those slices of the pie and devide each slice by the total

The sum of them all is 380 000. The 15 000 value is therefore (15000/38000)*100 percent of the pie (~4%). etc.

You need to sum the units and then calculate the percentage of the unit against the sum.

(Total of all the pie) ÷ 100 = percentage for that piece.
FTFY
Devide not times by

That will give you the value/% of 1 unit.

After that you need to calculate the various segments.

There are fomulas to calculate this.

With Pox here, Divide by total and times by 100.

15 000 + 75 000 + 90 000 + 200 000 = 380 000

15 000 / 380 000 X 100 = 3.95%
75 000 / 380 000 X 100 = 17.74%
90 000 / 380 000 X 100 = 23.68%
200 000 / 380 000 X 100 = 52.63%

For verification: 3.95 + 17.74 + 23.68 + 52.63 - 100% (well 98, but they're rounded so they won't be exact)

Hi. If I'm understanding your question correctly this is my solution.To work out % eg 15000.
15000/380000*100=3.95%
To work out degrees on pie chart eg 15000
15000/380000*360=14.21°
Where 380000 is the sum of 15000,75000,90000 and 200000.
Hope this helps.

Hi,

Thanks these were the most understood.
