Hello there!
If you divide the pie chart into fours, then each one will be 25%
Divide 25% in half, and you will get 12.5%
Therefore,
1. 12.5% Chose purple
Now if you want to get the amount of people:
360 divided by 100 = 3.6
3.6 times 25% (green)
2. 90 people Chose green
For the last one same principle:
(Blue) 90 people, (orange) 45
3. 45 (half) more people chose blue, over orange.
Hope this helps!
