Hi there,

To work out the percentage, divide 300 by 1000 and times the answer by 100 = 30%

or,just say, the results in a test are 72 out of 80, the percentage is 72 divided by 80 x 100 = 90%

hope this helps

To represent in a pie chart:

360 degrees / 100 = 3.6 degrees (for each 1%).

So for 30%, this would be 30 * 3.6 = 108 degrees.

Another value, of say £500 would be 50% and would need an angle of 50 *3.6 = 180 degrees.
