Twice as many of the clients have homeowners as home renters.
如果用数学语言的话，答案是H=2R.
为什么我觉得是2H=R？
那我的钢笔的数量是你的两倍，My pen is twice as much as yours.
这个怎么区分啊？

第一句的 have homeowners 可以置前，
由此变为 Homeowners have twice as many of the clients as home renters，
因此而有了 H(client) =
2*HR(client)
（这样就和
lz
举的那个钢笔的例子一样了；顺带一提，应该写成 My pens are twice as many as yours）
PS：我个人是很反感原句那种绕着弯的说法，毕竟涉及到计算的东西不应该像文学作品那样玩句式……
