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
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

A third is one of three equal parts of something. 这样解释明白吗？third也有三分之一的意思。

就是说Sally的（什么东西）是David的三分之一。你这句话前面应该还有一句话：某某是某某的三分之一，所以接着就说“again”。

a third again as many as 多达三次重复
a third as many again as 与...一样有三次重复

a third 三分之一
a third again 一又三分之一
设Dave有x，则：3/4x + x + 4/3x=111 得 x=36

参考答案错了
