分數/幾分之幾 的英文怎麼說?
分數 的英文怎麼說?
First, 分數的英文是:fraction
Second, 學幾分之幾之前,要先來認識「序數」
Let's go~~~
序數 ordinal numbers
來舉例一些序數吧:
基本數字 | 序數 | 基本數字 | 序數 |
1 | first (1st ) | 8 | eighth (8th ) |
2 | second (2nd) | 9 | ninth (9th ) |
3 | third (3rd ) | 10 | ten (10th ) |
4 | forth (4th ) | 11 | eleven (11th ) |
5 | fifth (5th) | 12 | twelfth (12th ) |
6 | sixth (6th ) | 20 | twentieth (20th ) |
7 | seven (7th ) | 21 | twenty-first (21st ) |
序數規律
first (1st ), second (2nd ), third (3rd ), fourth,…, nineteenth (4th,…, 19th )
twenty – twentieth (20th )
twenty-one = twenty-first (21st ), …., 29th
thirty – thirtieth (30th )
hundred – hundredth (100th )
thousand – thousandth (1000th )
some notes:
five –fifth
eight – eighth
nine – ninth
twelve - twelfth
小節-序數規律
從4 – 19,直接 + th
-ve 字尾,去ve + fth (five - fifth)
-e字尾,去e + th (nine - ninth)
-ty字尾(20,30,40…, 90),去y + ieth (thirty - thirtieth)
幾分之幾怎麼說~?
一般表示:
1/5: one-fifth1/20: one-twentieth
1/100: one-hundredth
分母為2,有「一半half」之意:
1/2: one-half
3/2: three-halves (分子>1,分母字尾+s。自偉為f,要去f+ves)
分子>1,分母字尾+s:
2/5: two-fifths
5/8: five-eighths
3/1000: three-thousandths
帶分數:
2 又 1/4: two and one-fourth6 又 2/15: six and two-fifteenths
那1/4怎麼說?
a quarter就是四分之一的意思囉~
總結~
分子是一般的數字,稱作基本數字;而分母則要用序數唷!
先說分子,再說分母
帶分數的「又」我們用and連接~
每次在文章或是練習題裡看到分數卻不知道怎麼表達嗎?
幾分之幾要怎麼說呢?
中文與英文的不同處在於邏輯
英文分數需要多想一下他是100%中的多少
舉例來說
1/10=10 % =one tenth
指得是100%的 10 %
1/4 =25% = a quarter
英文中的四分之一,因為是100%之中的25 %
所以,舉一反三 75 % = 3/4 = three quarter
此外,不論是時間或是分數都以quarter表示
那如果是1/5 = 20%= one fifth
大家一起來練習吧
