英語中“小數、分數、百分數”的正確表達

1. 小數表示法

(1) 小數點左邊的數通常按基數詞讀,若為三位以上的數,也可按編碼式讀法讀出,即將數字單個讀出;小數點右邊的數通常按編碼式讀法單個讀出。

如:

14.15 讀作: fourteen point one five

345.456 讀作: three four five point four five six

或讀作:three hundred and forty-five point four five six

(2) 小數中“0”的讀法,“0”在小數中通常讀作nought(英)或zero(美),也可讀作字母o。

如:

0.08 讀作:(nought)point nought eight

或讀作:(zero)point zero eight

9.07 讀作: nine point o seven

2. 百分數表示法

百分數中的百分號%讀作: percent。

如:

6% 讀作: six percent

0.6% 讀作: (nought) point six percent

500% 讀作: five hundred percent

3. 倍數表示法

倍數表示方法很多

如:

This room is four times as big as mine.

這個房間是我房間的四倍。

This room is three times larger than that one.

這個房間比那個房間大兩倍。

4. 分數表示法

(1) 較小分數的一般讀寫方法。

如:

1/3 讀作: one-third

2/3 讀作: two-thirds

(2) 較複雜分數的簡明讀寫方法。

如:

a/b 讀作: a over b 或 讀作a divided by b

43/97 讀作: forty-three over ninety-seven

(3) 整數與分數之間須用and連接。

如:

(4) 分數用作前置定語時,分母要用單數形式。注意下列寫法與讀法。
