1F：推 OohMyGOd:应该是1~99的正整数中是2也是3的倍数218.166.201.159 06/22 21:46
2F：→ OohMyGOd:也就是是6的倍数有几个218.166.201.159 06/22 21:47
3F：推 OohMyGOd:用 99/6 = 16.多 所以是16 也就是6 ~ 96218.166.201.159 06/22 22:02
4F：→ a8jr:谢谢，有恍然大悟的感觉 >< 61.231.141.144 06/22 23:17
5F：推 opie:答案确定对吗?不是16/99喔@@ 61.229.82.40 06/22 23:18
6F：→ opie:请问49是怎麽来的阿? 61.229.82.40 06/22 23:19
7F：推 a8jr:49是从98/2来的，因为1到99的整数中2的倍数 61.231.141.144 06/22 23:28
8F：→ a8jr:有49个，所以49是分母，然後6的倍数16当分子 61.231.141.144 06/22 23:29

13F：→ zhukov:看不懂,为何不是49当分子?是题目就这选项吗 125.225.23.170 06/30 00:36
14F：→ zhukov:有题考题What fraction of the number of 125.225.23.170 06/30 01:21
15F：→ zhukov:3 between 10 and 150 are also integer 125.225.23.170 06/30 01:22
