Among the users who obtained the "Organizer" badges, calculate the percentage of users who are teenagers.
"Organizer" is the Name of badge; teenager refers to Age BETWEEN 13 AND 18; percentage = Divide (Count(UserId where Age BETWEEN 13 AND 18), Count(UserId)) *100
SELECT CAST(SUM(IIF(T2.Age BETWEEN 13 AND 18, 1, 0)) AS REAL) * 100 / COUNT(T1.Id) FROM badges AS T1 INNER JOIN users AS T2 ON T1.UserId = T2.Id WHERE T1.`Name` = 'Organizer'
