最好能够翻译一下,不过到现在为止都看着有点混乱..
An apartment building has 5 floors,one of which has only 2 apartments.Each of the other floors has 4 apartments.
比较：
3 times the number of floors in the building
the number of apartments in the building
这个apartment 是什么？一个floor怎么会有2个apartment？
一个小孩从他的零钱罐里取出原始金额的10%，那么他必须再向存储罐中加入90分才能和原始金额一样多，问存储罐中原始金额是多少钱？
答：90分=0.9元
原始金额=0.9÷10%=9元
一个公寓大厦有5层，其中一层有两间公寓，其它层每层有4间公寓。
一个孩子从他的扑满地收回10%的原始金额在银行。如果他必须增加90 cnets带在银行数量恢复到原金额,什么是原始的金额在银行吗?
一个公寓大楼有5层,其中一个只有2公寓。每个楼层有4个公寓
我的理解是：孩纸从银行账户取出总额的10%.如果他要拿出90美分（cnets,我理解为cents不知道楼主你是不是打错字了.）才能与原账户存款一致,他的账户里面原先有多少钱?
楼主你自己斟酌一下下吧.
楼主你注意看,第一个是apartment building.指的是那种公寓式的住宅--就是后面提到的一层楼4个apartments一样,指的是公寓.用apartment是为了跟别墅什么的有区别.
