應該是1~99的正整數中是2也是3的倍數
06/22 21:46, 1F

06/22 21:47, , 2F
也就是是6的倍數有幾個

用 99/6 = 16.多 所以是16 也就是6 ~ 96

請問49是怎麼來的阿?
06/22 23:19, 6F

06/22 23:28, , 7F
49是從98/2來的,因為1到99的整數中2的倍數
06/22 23:28, 7F

06/22 23:29, , 8F
有49個,所以49是分母,然後6的倍數16當分子

看不懂,為何不是49當分子?是題目就這選項嗎

有題考題What fraction of the number of

06/30 01:22, , 15F
3 between 10 and 150 are also integer
06/30 01:22, 15F
