168. In a certain business, production index p is directly
proportional to efficiency index e, which is in turn
directly proportional to investment index i'. What is p if i = 70 ?
(1) e = 0.5 whenever i = 60.
(2) p = 2.0 whenever i = 50.
问题1:这个题A is directly proportional to B 就是成正比的意思吧? 请问下成反比怎么表达啊?
问题2: P= 2 Whenever I = 50 的含义是,当I=50, P为2吧? 还是反之啊?
感谢好心人赐教哦。哈哈作者: viviansecret 时间: 2013-2-3 07:13

反比的表达是 inverse proportion
问题2: P= 2 Whenever I = 50 的含义是,当I=50, P为2吧? 还是反之啊?
和你理解的一样:当I=50, P=2
