Question: Which organization has the highest number of male students? Calculate for the percentage of the male students in the said organization.
Evidence: organization refers to organ; highest number of male students refers to MAX(COUNT(male.name)); percentage = DIVIDE(COUNT(male.name), COUNT(person.name)), 1.0;

SQL:
SELECT T.organ, T.per FROM ( SELECT T1.organ, CAST(COUNT(T3.name) AS REAL) / COUNT(T2.name) AS per , COUNT(T3.name) AS num FROM enlist AS T1 INNER JOIN person AS T2 ON T1.name = T2.name LEFT JOIN male AS T3 ON T2.name = T3.name GROUP BY T1.organ ) T ORDER BY T.num DESC LIMIT 1
