各种分数的英文读法

各种分数的英文读法
你是否对于分数如何用英语表达出来感到云里雾里?其实说到底它的表达跟我们的基数词和序数词有关系。
比如:基数one,two,three的序数词是once,twice,third。
但是我们一般不用once和twice。
我们看下面的例子。
一、英语分数表达法,英语分数读法:
1.用英文单词表示分数时,一般情况下,分子用基数词,分母用序数词:
1/2 二分之一英语读作:one half 或者a half(这里的one和a代表“一”,half 代表“二分之”);
1/8 八分之一英语读作:one-eighth;
1/3 三分之一英语读作:one third 或者a third;
2.当分子大于1时,分母须用序数词的复数形式。
表达分数时,基数词与序数词之间常加“-”,“-”有时可以省略:
2/3 三分之二英语读作:two thirds或者two-thirds;
3/4 四分之三英语读作:three quarters 或者three fourths(“四分之”可以用quarters或者fourths来表示);
4/5 五分之四英语读作:four-fifths 或者four fifths;
7/8 八分之七英语读作:seven-eighths 或者seven eighths;。

英语中各个成分的线条表示方法

英语中各个成分的线条表示方法1. 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: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。
However, the number of the boys will be less than a third of the girls in the class.但是班里男生的人数将比女生的三分之一更少。
*从以上例子可以窥见:分子为1时,既可以用 one,也需用a。
2. 如果分子大于1,分母则要用复数形式。
如:三分之一 one-third;三分之二 two-thirds3. 二分之一不能说 a second,而要说 a half。
四分之一和四分之三可以说道 a fourth 和 three-fourths,但常用 a quarter 和three quarters 则表示。
4. 分数修饰的名词在句子中作主语时,谓语动词是用单数还是复数取决于名词,即与名词保持一致。
如:Only one-fifth of air consists of oxygen.氧气只占空气的五分之一。
About two thirds of the students are going to attend the meeting.大约三分之二的学生都将参加会议。
5. 带分数的则表示: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。
如:You should finish the work within one and a fourth hours.你应在1小时25分钟内完成工作。
6. 分数常和 of 属格,并作主语或宾语,但分数也可以不拎 of 短语轻易并作主语或宾语。
英语中分数的表示方法

英语中分数的暗示方法:之袁州冬雪创作一、用“基数词+序数词”暗示分数在英语中通常是借助于表达的.其中基数词暗示分子,序数词暗示分母.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不克不及说a(one)second,而要说a(one)half.例如:3.The sum of one half,one third and number is 13.某数的1/2,1/3和1/4的和是13.1/4和3/4可以说a(one)fourth和three fourths,但常常使用a quarter和three quarters暗示.应该注意的是,分数修饰名词时,若该名词是不成数名词只能用单数;若是可数名词,用单数或复数都可.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坚持一致.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的学生都参与了会议.带分数也是罕见的英语数词表达.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毗连.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,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.7.The atom breaks up in a minute and a quarter.原子在1.25分钟内裂变.二、用percent等暗示暗示百分之一可以说one(a)hundredth,但更常常使用one percent或per cent,即用百分数暗示法来表达.例如:8.Our water.我们人体含65%水分.9.Seventy-five percent of the earth’ssur- face is covered by water.地球概况的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暗示名词part有“……分之一”的意思,分子大于1时,part用复数.暗示分数的布局一般有以下三种:(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 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”暗示借助介词暗示分数,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.这种布局中的介词主要有in,out of,of以及to12.The map is drawn to a scale of one of ten thousand.这张地图是的.。
英语中分数的表示方法

英语中分数的表示方法In English, there are several different ways to express and represent fractions and percentages. Understanding these different methods is important for both academic and practical purposes. In this document, we will explore the various ways in which fractions and percentages are represented in English, and how to use them in different contexts.One of the most common ways to represent fractions in English is through the use of the forward slash (/). For example, the fraction one-half is written as 1/2. This method is simple and easy to understand, and is commonly used in both written and spoken English. Another way to represent fractions is through the use of the word "and". For example, the fraction three and a half is written as 3 1/2. This method is often used in informal contexts, such as when discussing measurements or cooking recipes.When it comes to representing percentages, the most common method is through the use of the percent sign (%). For example, 50% represents fifty percent. Percentages are used to express a proportion out of 100, and are commonly used in a wide range of contexts, such as in finance, statistics, and everyday conversation.In addition to these methods, there are also other ways to represent fractions and percentages in English. For example, fractions can be written in decimal form, such as 0.5 for one-half. Percentages can also be written in decimal form, such as 0.50 for fifty percent. These forms are often used in technical or scientific contexts, and are important for understanding and working with numerical data.It is important to note that different English-speaking countries may have different conventions for representing fractions and percentages. For example, in some countries, a comma is used instead of a decimal point to separate the whole number from the fraction or percentage. It is important to be aware of these differences when communicating with people from different regions.In conclusion, there are several different methods for representing fractions and percentages in English, including the use of the forward slash, the word "and", thepercent sign, and decimal form. Understanding these different methods is important for effective communication and for working with numerical data in a variety of contexts. By being aware of these different representations, you can improve your English language skills and your ability to work with numbers in a range of situations.。

英语分数的读法规则如下:
1. 先读分子,再读分母。
分子用基数词表示,分母用序数词表示。

基数词+序数词
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可以说a(one)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。
