Hello there! I think it is a) 59%. So what I did is add all the numbers 51, 23, and 12 all together. So then I did 100/86= 1.162279068767. Then I did 1.162279068767*51= 59%(approximately).(That is only for the frequently!)
For both of them together it would be 86%( I rounded) So I did 1.162279068767*23. Then I add the 59%+26%= 86. That is how I got the answer.
