请教一个关于倍数表达的问题

cclovelife

在做题的时候发现自己关于倍数的表达理解上竟然有偏差，而且一下子还绕不过来，在这里弱弱的请教大家T T

this three is three times as tall as that one.   这棵树的高度是那棵树的三倍，这个没问题


there are 3 times as many girls as boys in the class.     G=3B, 我怎么看都觉得是3G=B啊.....抓狂....


还有一个类似的，it takes 6 times as long to run the cartoon as it takes to rewind the film.
run the cartoon=a; rewind the film =b;  因此a=6b.....


我就是怎么琢磨都觉得是反过来3G=B, 6a=b......不知是理解句子哪里出了问题......
问题比较弱智，还是恳求各位大侠给指点下迷津，不胜感激.....
