hi

我 是 phyllis

我要ㄉ是答案拉!!!

謝囉!!

樓上的朋友,

我想的跟你一樣耶!

但是我想既然是"數學問題"

老師應該要的是"答案"而不是"題意"吧

Phyllis, 你下次也說清楚講明白唄!

Dear Nuee,

我數學不是很好

但是第二題以我的想法算 是 "5/24" 沒錯

Two possitive integers have a sum of 30 and a product of 144. Find the sum of the reciprocals of two integers.

有兩個正整數,總合為30,乘積為144.

請找出這兩個整數的倒數的總合.

這兩個整數應該是 6 還有 24

所以他的倒數就是 1/6+1/24=5/24

請提問的人老師給了正確答案也要po上來一下呀!
