英语分数的表示法：）~~
一、用“基数词＋序数词”表示
分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子，序数词表示分母。
如：
1．The centimeter is one-tenth of the decimeter or one-hundredth of the meter．厘米是分米的十分之一，或者说是米的百分之一。
2．However，the number of boys will bea third or less than the girls in the class．但是，班里男生的人数将比女生少三分之一或更少。
从以上例子可以看出：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。但是，1／2不能说a（one）second，而要说a（one）half。例如：
3．The sum of one half，one third and one fourth of a certain number is 13.某数的1／2，1／3和1／4的和是13。
1／4和3／4可睁肆枯以说a（one）悉洞fourth和three fourths，但常用a quarter和three quarters表示。应该注意的是，分数修饰名词时，若该名词是不可数名词只能用单数；若是可数名词，用单数或复数均可。但是，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。例如：
4．Only one-fifth of air consists of oxygen．氧气只占空气的1／5。
5．About two thirds of the students attendthe meeting．大约2／3的学生都参加了会议。
带分数也是常见的英语数词表达。所谓带分数，实际上是“整数＋分数”，表达时分而述之，只是整数部分与分数部分要用连词 and连接。当带分数修饰名词时，该名词通常是复数，但若名词置于整数one或a之后，则用单数。“带分数＋名词”作主语时，谓语动词根据临近原则要用复数。例如：
6．You should finish the work within one and a fourth hours．你应在1．25小时内完成工作雹伍。
7．The atom breaks up in a minute and a quarter．原子在1．25分钟内裂变。
二、用per cent等表示
表示百分之一可以说one（a）hundredth，但更常用one percent或per cent，即用百分数表示法来表达。例如：
8．Our bodies are 65percent water．我们人体含65％水分。
9．Seventy-five percent of the earth'ssur- face is covered by water．地球表面的75％被水覆盖着。
10．Eighty-five percent of the students in English department are girls．英语系85％的学生是女生。
三、用part表示
名词part有“……分之一”的意思，分子大于1时，part用复数。表示分数的结构一般有以下三种：
（1）“基数词（或a）＋序数词＋part（s）” a hundred part百分之一
（2）“基数词＋part（s）＋in＋基数词” five parts in one thousand千分之五
（3）“基数词＋part（s）＋per＋基数词” one part per million百万分之一
四、用“基数词＋介词＋基数词”表示
借助介词表示分数，介词前的数词是分子，介词后的数词是分母。例如：
11．Ninety-nine people out of a hundred，if they were asked who first found America， would answer Clumbus．如果要问是谁首先发现美洲，一百个人中有九十九个（百分之九十九）将回答是哥伦布。
这种结构中的介词主要有in，out of，of以及to
