请教一个倍数的问题，一直未得到明确答案

izkuki

A school has 3 times as many boys as girls.

究竟是girls是boys的3倍，还是反过来的。

复习的时候，类似的问题，答案都是前者。但网上语法都说的是后者。

确实不懂了。

望专家能把倍数的其他表达方式也能总结一下，谢谢。

as many as的意思是和。。。一样多，eg。as many as you want，就是和你想要的一样多，因此A school has 3 times as many boys as girls就是女生的数量是男生的三倍一样多

严重错误，应该是男生是女生3倍

n times as many A as B, B  是基数，A与B的比较倍数就是N

我的数学讲义上写着，twice as many A as B 相当于 A=2B
楼主这句话，应该是 男生数量=3*女生数量

A as many as B ，B是被比较的对象，

3 times as many boys as girls =boys is 3 times as many as girls

也就是男是女的三倍。

我只能说大多数人都支持男是女生的三倍。

刚问了一个哈佛的native speaker, 他的解答是：
A school has 3 times as many boys as girls.".

Boys' number = 3 x Girls' number
