英语分数的表示法： 用“基数词＋序数词”表示，分子用基数词，分母用序数词。分子除用one外，也可用a；如果分子大于1，分母要用复数形式。
Two thirds of the students have passed the exam. 三分之二的学生考试及格了。
注意：1／2不能说a（one）second，而要说a（one）half。
1／4和3／4可以说a（one）fourth和three fourths，但常用a quarter和three quarters表示。
若它们在句子中作主语，则谓语动词是用单数还是复数取决于名词，即与分数所修饰的名词保持一致。
About two thirds of the students attend the meeting．
大约2／3的学生都参加了会议。
6. Hang on a minute!
通常用来表示让某人等一下。
e.g. Hang on! I’ll be back in a minute.
朗读时，将每三位数看做一个单位，依次为billion，million，thousand。每个单位按照百、十、个位向下读，其中百位到十位之间要加入 and。
e.g. 729 ：seven hundred and twenty nine.
6,500,431,729：six billion five hundred
million four hundred and thirty one
thousand seven hundred and twenty nine.
在英语中，对于万以上的数字，我们改如何表达呢？这就要记住英语数字读法特点。以下面一个数字为例：
6，500，431，729
hundred
thousand
million
billion
注意每三个数为一个单位，按照百、
十、个向下读。
