Pie charts
If you want to find out how many percentages one person is you add up all of the percentages on the pie chart and divide by how many people are in the survey. eg if there is 30 people in the survey divide by 360 equals 12. Then divide the percentages by 12. 360/30= 12 Then 40/12, 150/12, 80/12 and 90/12. That will tell what the percentage is per person.
When drawing a pie chart you must use a protractror and ruler and you must draw the circle with a compass.
