求问一道英语选择题,我不知道这题该如何理解
Sally had a third again as many as David,who had a third as many again as Francis.Altogetter they had 111.How many did David have?
这句话里a third
答案说算出来是36
答
是一道数学题
萨利的东西是大卫的三倍,大卫的东西是弗朗西斯的三倍,他们三人总共有111,问大卫有多少我本来也是这么理解的，但是答案说算出来是36，按这个理解算不出来36这个数啊a third again是三分之四的意思，就是一又三分之一 后面也是三分之四，这样能够凑出111 这个结果 483627=111
