Expressing numbers in English can be confusing to both students and those listening. Make sure you understand how to express numbers in spoken English by following these rules.用英語表達數字，無論是對學生還是聽者來說都是容易令人困惑的。通過遵循以下這些規則，可以確保你懂得如何用英語表達數字。
Below you will find numbers written out in order to helps students learn the correct grouping in English. Generally speaking, numbers larger than twenty should always be expressed by numbers in written English:你會發現下面寫出的數字是為了幫助學生學習正確的分組。一般來說，大于二十的數在書面英語中應該用數字表示：
I have fifteen clients in New York.
She has 240 contacts on her mailing list.
Say individual numbers between one and twenty. After that, use the tens (twenty, thirty, etc.) followed by the numbers one through nine:一到二十之間，我們讀單個的數字。二十往后，使用十位數（二十，三十等），緊接數字一到九：
When expressing large numbers (more than one hundred) read in groups of hundreds. The order is as follows: billion, million, thousand, hundred. Notice that hundred, thousand, etc. is NOT followed by an "s"當表達大數字時（超過一百），以“百”為單位來讀。順序如下：十億，百萬，千，百。請注意，百、千等詞后面不加“s”
Two hundred NOT two hundredsTwo hundred不是two hundreds
Say numbers in the hundreds by beginning with numerals one through nine followed by "hundred". Finish by saying the last two digits:讀百位數以一到九開始，緊接著“hundred”，以末尾的兩位數結束：
350 – three hundred fifty
425 – four hundred twenty-five
873 - eight hundred seventy-three
NOTE: British English takes "and" following "hundred." American English omits "and:".注：英式英語會在“hunderd”后加上“and”。美式英語則省略“and”。
The next group is the thousands. Say a number up to 999 followed by "thousand." Finish by reading the hundreds when applicable:下一組是千位數。先讀出999以內的數字，后面緊接“thousand”，然后必要時，以百位數來結束。
15,560 – fifteen thousand five hundred sixty
786,450 – seven hundred six thousand four hundred fifty
342,713 - three hundred forty-two thousand seven hundred thirteen
569,045 - five hundred sixty-nine thousand forty-five
For millions, say a number up to 999 followed by "million." Finish by saying first the thousands and then the hundreds when applicable:對于百萬位的數，先讀出999以內的數字，后面緊接“million”，然后必要時，先以千位數，再以百位數來結束。
2,450,000 – two million four hundred fifty thousand
27,805,234 - twenty seven million eight hundred five thousands two hundred thirty-four
934,700,000 – nine hundred thirty-four million seven hundred thousand
589,432,420 - five hundred eighty nine million four hundred thirty-two thousand four hundred twenty
For even larger numbers, first use billions and then trillions in a similar manner to millions:對于更大的數字，先用十億位，再用萬億位，然后以相同的方式表達百萬位。
23,870,550,000 - twenty-three billion eight hundred seventy million five hundred fifty thousand
12,600,450,345,000 - twelve trillion six hundred billion four hundred fifty million three hundred forty-five thousand
Large numbers are often rounded to the next biggest or next smallest number to make things easier. For example, 345,987,650 is rounded to 350,000,000.過于大量的末尾數往往被舍入到下一位最大或最小的整數，這樣就使讀數變得更容易。例如，345987650被舍入到350000000。
Speak decimals as the number followed by "point." Next, say each number beyond the point individually:讀小數就讀出數字，緊接著加上“point”。然后后面的數字分別單獨來讀就行。
2.36 - two point three six
14.82 - fourteen point eight two
9.7841 -nine point seven eight four one
3.14159 - three point one four one five nine
Speak percentages as the number followed by "percent"
37% - thirty-seven percent
87% - eighty-seven percent
Speak the top number as a cardinal number, followed by the ordinal number + "s"分數線上面的數字讀基數詞，分數線下面的數字讀序數詞加“s”。
Exceptions to this rule are:
1/4, 3/4 - one-quarter, three quarters
1/3, 2/3 - one third, two-thirds
Read numbers together with fractions by first starting the number followed by "and" and then the fraction:讀帶分數的方法是先讀前面的數字，再加上“and”，然后讀分數。
4 7/8 - four and seven-eighths
23 1/2 - twenty-three and one-half
