If s and t are positive integers such that s/t=64.12 ,which of the following could be the remainder when s is divided by
A/ 2
B/ 4
C/ 8
D/ 20
E/ 45

If s and t are positive integers such that s/t=64.12 ,which of the following could be the remainder when s is divided by A/ 2B/ 4C/ 8D/ 20E/ 45
设s除以t的余数是x,那么x/t=0.12,注意题目中说s,t都是整数.
将最简0.12化成分数形式0.12=3/25=x/t
那么x=3k；t=25k； k为整数.
显然选项中是3的倍数的只有E、45
楼上说的也对,因为t=x/0.12,但是这里还不不能用整除这个概念,这能说结果为整数

应该是E 45 看 哪个数字可以被0.12整除 就是答案、
哎 我还回答个什么劲。
LZ不知道取第一个正确答案这个原则吗？
