题目没有说A:B:C的比值必须是整数，所以可以出现比值为小数的情况，这样123:456:789的比值就是1:3.xx:6.xx ,满足条件的也就为123 456 789了。加上求比值的操作和注意类型应该就过了。

@lnnau 为什么A，B，C可以是小数？我不明白qwq

by bowenzuo @ 2022-11-28 11:22:09

@lnnau 三个数的比可以是小数么？

by lnnau @ 2023-03-18 15:36:43

@bowenzuo 是比值是小数，不是说ABC是小数

by lnnau @ 2023-03-18 15:37:00

@bowenzuo 对

by bowenzuo @ 2023-03-18 15:40:51

@lnnau 哦
