英语翻译
What fraction of the positive intergers that are multiples of 30 and are less than or equal to 360 are multiples of 12

$英语翻译What fraction of the positive intergers that are multipl$

问题的意思是,能被30整除的数,而且小于等于360,这些数有多少可以被12整除,比例是多少?
可以被30整除的,30,60,90,120,150,180,210,240,270,300,330,360
其中可以被12整除的,60,120,180,240,300,360
比例是6/12,也就是50%
简便的算法：360/30,也就是说360内,12个整数被30整除
30和12的公倍数,60,360内,6个整数被60整除
6/12=0.5
再问：给跪了。。。为什么我看的是“能被30整除的数”与“小于360且能被12整除的数”的比例是多少呃？。。我问题出在哪了？
再答： What fraction of the positive intergers 这个是求比例 that are multiples of 30 and are less than or equal to 360 这个是说小于等于360且被30整除的数 are multiples of 12 ? 这个是被12整除 are前面都算作are的主语吧 LZ，我考也是10年前的事情了，现在基本都丢掉了，也没那么有把握，你还是要自己掂量下。祝考试顺利
