Answer:
Ricky ran 16.66% more of the track than Leena
Explanation:
First, we find how much each ran as a percentage.
Leena ran 2/3 of the track
As a percentage, Leena ran:
2*100%/3 = 66.67%.
Ricky ran 5/6 of the same track.
As a percentage, Ricky ran:
5*100%/6 = 8333%
Thus Rick ran more, by 83.33% - 66.67% = 16.66%.
