319. special stock, 付给5cents, 每3 of 4 quaters of the year; normal stock, 40 cents, 每4 quaters of the year. 问for each share, the fraction of special stock to the total stock...选项都是分数,分母有175,45,分子忘了
我想问的不是解法。。。是想问3 of 4 quaters of the year和4 quaters of the year是什么意思?
3 of 4 quaters是不是就是说(3/4)*4个月=3个月? 然后4 quaters of the year就是指1年12个月呢?
