问题 Questions are based on the following data.
[br] For the biological sciences and health sciences faculty combined, 1/3 of the female and 2/9 of the male faculty members are tenured professors. What fraction of all the faculty members in those two fields combined are tenured professors? Give your answer as a fraction.
选项
答案 8/29
解析 首先求出生物学和生命科学总人数(combined faculty)：200×(5％+16％)+250×(10％+8％)=87。然后求两个学科的终身教授人数(tenured professors)：200×(5％+16％)×1/3+250×(10％+8％)×2/9=24。所以终身教授/总人数=24/87=8/29。
