Numbers in English can be a little tricky for learners, especially to write. Sure, in all of the languages that use the Latin alphabet, the digits are written the same. For example, the number 5 is the same in English and Spanish, but it is said differently and written out in letters differently. We created this article about how to say and write the numbers in English for anyone who struggles with this common part of the English language. It includes a free study guide that you can download and print out!

More English Numbers: Ordinal Numbers

  • The ordinal numbers in English [first, second, third] are used to order things. They are normally used as determinants, that is, before the subject of the sentence.
    • Example: This was the third exam she passed.
  • They are also used to refer to dates, and there is an abbreviated form of each of them.
    • Example: My birthday is November 3rd. When talking about dates, you can also add the word [the], like this: [the third of November].
  • The abbreviations of cardinal numbers as follows. Notice that only the first three are different—all the rest use “th”:
    • first [e.g. 1st]
    • second [e.g. 22nd]
    • third [e.g. 23rd]
    • fourth [e.g. 24th]
    • fifth [e.g. 25th]
    • sixth [e.g. 26th]
    • seventh [e.g. 27th]
    • eighth [e.g. 28th]
    • ninth [e.g. 29th]

More English Numbers: Fractions

  • To refer to fractions in English, use the cardinal number for the numerator and the ordinal number for the denominator.
    • Example: 1/3 would be [one third]
  • When the numerator is greater than 1, the denominator has to be in the plural form. Therefore, you need to add an s at the end.
    • Example: 5/6 would be [five sixths].
    • The only exception is 2, which is expressed as [half] when the numerator is 1 (ex. ½ is one half) and [halves] when it is greater than 1 (ex. 3/2 would be three halves).

How to Pronounce English Numbers (VIDEO)

Now, if that all seems a little complicated, Abbe will explain everything you need to know about the numbers in English and how to pronounce them in the video below. You can also watch it on our YouTube channel. Repeat each number out loud after Abbe to practice your pronunciation. That’s called shadowing; read this article to learn more about the shadowing technique.

How to Write Numbers in English

Number conventions are different in every language, and it’s important to get them right. This is a slightly more advanced topic, so if you’re a beginner you can stick to learning the basic numbers above.

Decimals in English

  • To write them, use a period (.) to separate the whole number from the rest. (Be careful, your native language might use a comma (,) instead, but in English we can only use a period.)
  • To say the number, use the word [point] and, right after, the decimal number.
    • Be careful: the number zero is usually omitted in spoken English.
    • Example: 0.5 would be [point five].

Percentages in English

  • First, write the number followed by the percent symbol (%). To put it in words, it’s easy. Just use the word [percent].
    • Example: 33% is [thirty-three percent].

English expressions with decimals and percentages: “99.9% (ninety-nine point nine percent)” — almost certain, almost always, almost completely. For example, “I am 99.9% sure I locked the car,” you are nearly certain that you locked the car.

Prices in English

  • To talk about money, first say the full dollar amount, then the name of the currency. Be sure to make the currency plural if you are talking about more than one: dollars, pounds, euros, rupees, etc. If there are cents, they go at the very end. You can also shorten it when it’s clear what currency you’re talking about, as in the second part of the example below. Say the dollar amount then the cents amount, with nothing in between.
    • Example: $12.66 would be [twelve dollars and sixty-six cents] or [twelve sixty-six].
  • Someone might ask for change using the name of the coin instead of the amount of cents. Therefore, it’s worth knowing the common coins in US currency:
    • 1¢ = one cent = a penny
    • 5¢ = five cents = a nickel
    • 10¢ = ten cents = a dime
    • 25¢ = twenty-five cents = a quarter

English expressions with currency: “to put in one’s two cents” — to provide your opinion, usually when no one asked for it.

How to say 0 in English

Next, there are different words for the number zero depending on the use. They are the following:

  • Oh for digits (e.g. phone numbers, door codes).
    • Example: 57640 would be [five-seven-six-four-oh]
  • Zero for measurements (e.g. temperature).
    • Example: -7º would be [seven degrees below zero]
  • Nil for sports scores, especially in British English. Americans might call this “zip,” but it is quite informal.
    • Example: 35 – 0 is [the match ended thirty-five – nil]

 

BONUS: Telling Time in English

Telling time and talking about the date in English are other useful skills to have. They also deal with numbers, but they are a bit particular. Watch Abbe’s video to learn how to use the English numbers you just learned to make an appointment or give someone the time.
