One night, in order to welcome new students, a film projection company went to a certain school to show an open-air movie. Some of the audience were standing and the other were sitting. If 35% of the standing people sat down, and 35% of the sitting people stood up, then the standing people accounted for 3/5 of the audience. How much?
一天晚上，为欢迎新同学，电影放映公司到某学校放映露天电影，观众中一部分站着，另一部分坐着．如果站着的人有35%坐下，而坐着的人中有35%站起来，那么站着的人就占观众人数的(3/5)，原来站着的观众占观众总人数的几分之几？
