4. 52/360=13/90 or .14444 or 14.444%
5. 200/360=5/9 or .55556 or 55.556%
6. 252/360=7/10 or .7 or 70%
Since there is a total of 360 degrees in a circle, any probability taken out of the circle would be out of 360. All you need to do is create a fraction based off of the values given and simplify. My simplified fractions are shown in the answers above.
Hope this helps! :)
