英语分数、小数及百分数的表达



1.


表达形式



⑴分数



①基本规则:子基母序(即:分子用基数词,分母用序数词)



1/3 one third 1/8 one eighth 1/12 one twelfth


②当分子大于


1


时, 分母要加


s


变成复数。



2/3 two thirds 3/8 three eighths 5/12 five twelfths


③特殊的表达:



1/4


可以表示为


one fourth


或者


a quarter


3/4


可以表示为


three fourth


或者


three quarters


1/2 a half


⑵.小数


< /p>


小数点前后的数均按基数词来读,小数点读成


point




小数点后的数字逐位读


出。



3.1415926 three point one four one five nine two six


0.463 zero point four six three


⑶.百分数



汉语中先读 百分号,再读数字;英语中恰恰相反:先念出数字,再加上百分号


percent


80% eighty percent


99.5% ninety-nine point five percent
