Answer:
14%
Explanation:
first, you would have to find how many skittles there are in total. You would add the red, blue, green, and purple skittles together and get 72. Next you would take the number of red skittles (10) and put it over the number of total skittles (72) and get the fraction 10/72. Lastly divide 10 by 72 and get the decimal .13888889 which would round up to .14 move the decimal over 2 places and get 14%
hope this helped :)
