请教数学倍数表达方法...n times as many x as y

放耳朵去流浪

there were n times as many x as y 意思是。。。？

A costs 3 times as much as B 意思是。。。？？？

哪位大神解答一下呢？

我之前也困惑过这个问题，应该是A的cost＝B的cost * 3

x/y=n; A/B=3

x/y=n; A/B=3

感谢哦，这个 x=ny是怎么理解的呀 是靠分析句子成分么还是怎样 感觉超奇怪的

其实按照句意就是应该理解成 x比y=n 变形一下是x=ny

A costs 3 times as much as B 意思是。。。？？？

英文：There are 3 dogs.
中文：有三隻狗
數學：狗的數量是3

英文：There are as many dogs as pigs.
中文：狗跟豬一樣多
數學：狗的數量等於豬的數量
** as many.... as pigs 意思就是"跟豬一樣多" 或者想成"the number of pigs"

英文：There are 3 times as many dogs as pigs
中文：狗有豬的三倍
數學：狗的數量等於3乘以豬的數量
** 3 times 就是乘以3，修飾 as many... as pigs

最後一著爛招(如果出題老師不是太狠心的話，OG/PP/GWD的PS裡面用這招有超過一半的時候管用)
不確定是 X=3Y 還是 Y=3X，那就先選一種，計算看看，如果五個選項沒有答案或者算出不合理(例如動物的數量不是整數)
那就知道一開始選錯了
