关于数学中的比较用语？

pite123

1： 9 times as many paperback copies as hardback copies

9 times paperback copies = hardback copies

2: if 2/3 as many dozen were sold in April as in May , and twice as many were sold in June as in April

若April is x, then may=3/2x june=2x

自己遇到这种比较题目，就晕，请问这种东东如何分析？谢谢了。

我给这样的题做了一个总结:

n times as many A as B 就是

A=n*B

所以第一题应该是paperback copies=9*hardback copies

paperback发行后可以得到这样的等式:

p+h=441000-36000

9h+h=405000

h=40500进而p=9h=40500*9=364,500
