Numbers in English

Cardinal numbers, ordinal numbers, big numbers, fractions, decimals, dates, money, and everyday usage

Numbers look simple. Then English shows up and says, “Great, now say one hundred and five, the third floor, half past six, and $4.99 without panicking.” Charming.

This guide breaks down the most useful number patterns in real English. You will learn how to say numbers clearly, use them naturally, and avoid the mistakes that make native speakers quietly wince.

By the end, you will understand the main number types and be able to use them in everyday speech, writing, shopping, dates, and more.

1. Cardinal Numbers: Counting Things

Cardinal numbers are the basic counting numbers: one, two, three, four, and so on. They answer the question How many?

Use them for people, objects, prices, age, distance, and many other everyday situations.

Number	Pronunciation Help	Meaning	Example Sentence	Learner Note
one	won	1	I have one brother.	Use with singular nouns.
two	too	2	We need two tickets.	Simple and very common.
three	three	3	There are three chairs.	Watch the “th” sound.
four	for	4	She has four books.	Sounds like “for,” but it is a number.
five	fai-v	5	He bought five oranges.	Common in shopping and counting.
ten	ten	10	The class has ten students.	Important for prices and time.
twenty	TWEN-tee	20	She is twenty years old.	Stress is on the first syllable.
thirty	THUR-tee	30	We live thirty miles away.	Do not say “three-ty.”
forty	FOR-tee	40	The trip takes forty minutes.	Spelling note: no “u” in American English.
one hundred	won HUN-dred	100	The hotel has one hundred rooms.	“A hundred” is also very common.

Grammar note: Use singular nouns after one, and plural nouns after numbers bigger than one.

one apple
two apples
five emails
ten dollars

English usually does not need and in small numbers in American English. British English often uses and more often in large numbers.

American English: one hundred five
British English: one hundred and five

Both are correct, but if you want to sound more American, skip the and in that type of number.

2. Ordinal Numbers: Order And Position

Ordinal numbers tell position or order: first, second, third, fourth, etc. They answer Which one?

Ordinal	Pronunciation Help	Meaning	Example Sentence	Learner Note
first	furst	1st	I was first in line.	Very common in rankings and dates.
second	SEK-und	2nd	This is my second cup of coffee.	Useful for time and order.
third	thurd	3rd	She lives on the third floor.	Watch the spelling and “th” sound.
fourth	FORTH	4th	It is the fourth chapter.	Often used with floors, chapters, and dates.
tenth	tenth	10th	His birthday is on the tenth.	Common in dates.
twentieth	TWEN-tee-ith	20th	The twentieth question is difficult.	Longer, but useful.

Common spelling pattern: many ordinals add -th to the number word.

four → fourth
six → sixth
seven → seventh
nine → ninth

Important exception: one, two, and three become first, second, and third.

3. Big Numbers: Hundreds, Thousands, Millions, And Beyond

Big numbers can make learners nervous, but the pattern is actually pretty calm. English builds large numbers in a clear order: hundreds, thousands, millions, billions.

Number	Pronunciation Help	Meaning	Example Sentence	Learner Note
100 / one hundred	HUN-dred	100	There are one hundred pages.	“A hundred” is also natural.
1,000 / one thousand	THOW-zund	1000	The event has one thousand guests.	Use comma separators in writing.
10,000 / ten thousand	TEN THOW-zund	10000	The town has ten thousand people.	Very common in reports and news.
100,000 / one hundred thousand	HUN-dred THOW-zund	100000	It costs one hundred thousand dollars.	Keep the order clear.
1,000,000 / one million	MIL-yun	1 million	The city has one million residents.	Often shortened to “a million.”
1,000,000,000 / one billion	BIL-yun	1 billion	The company is worth one billion dollars.	In American English, a billion = 1,000 million.

Number order tip: Read large numbers in chunks.

1,245 = one thousand two hundred forty-five
18,300 = eighteen thousand three hundred
2,450,000 = two million four hundred fifty thousand

In American English, people often say large numbers in a compact way. For example, 1,200 may sound like twelve hundred, especially in everyday speech.

Big numbers are not difficult. English just wants you to say them in the right order and not freestyle like a confused robot.

For a boring but useful reference, see Cambridge Dictionary.

4. Fractions: Part Of A Whole

Fractions describe parts of something: half, one-third, three-quarters.

Fraction	Pronunciation Help	Meaning	Example Sentence	Learner Note
half	haf	1/2	I ate half the pizza.	Very common in food, time, and amounts.
a third	uh thurd	1/3	One third of the class was absent.	Use “a” for 1/3.
a quarter / one-fourth	KWOR-ter / wuhn FORTH	1/4	I need a quarter cup of sugar.	Quarter is very common in American English.
two-thirds	too THURDZ	2/3	Two-thirds of the students passed.	The plural thirds shows more than one part.
three-quarters	three KWOR-terz	3/4	The bottle is three-quarters full.	Common in measurements and descriptions.

Useful pattern: When the top number is greater than 1, the bottom number is usually plural.

1/2 = one half
2/3 = two thirds
5/8 = five eighths

Learner note: half is very common in time expressions too: half past six means 6:30, especially in British English. In American English, people often say six thirty.

5. Decimals: Numbers With A Point

Decimals are used for measurements, prices, statistics, and scientific information. In English, the symbol . is called a decimal point.

Decimal	Pronunciation Help	Meaning	Example Sentence	Learner Note
0.5	zero point five	one-half	The package weighs zero point five kilos.	Say each digit after the point.
1.2	one point two	1.2	The train is one point two miles away.	Very common in measurements.
3.14	three point one four	3.14	Pi is about three point one four.	Read digits one by one after the point.
12.75	twelve point seven five	12.75	The price is twelve point seven five dollars.	Use with money, science, and data.

Important rule: After the decimal point, English usually says each digit separately.

4.08 = four point zero eight
9.50 = nine point five zero or in money, often nine fifty
2.01 = two point zero one

Common mistake: Do not say four and zero eight for 4.08. That sounds like a math problem that wandered into a bank.

6. Dates: Days, Months, And Ordinal Numbers

English dates often use ordinal numbers. That means 1st, 2nd, 3rd, 4th, not just 1, 2, 3, 4.

Format	Example	Meaning	Learner Note
Month + day	July 4	The fourth day of July	Very common in American English.
Month + ordinal	July 4th	The fourth day of July	The “th” is often written in casual style.
Day + month	4 July	The fourth of July	More common in British English.
Full spoken date	July fourth, twenty twenty-five	July 4, 2025	Natural spoken American English.

American vs British difference:

American English: July 4, 2025
British English: 4 July 2025

When speaking, Americans often say:

July fourth
January first
October twenty-third

For years, English usually reads each pair or group naturally:

1998 = nineteen ninety-eight
2020 = twenty twenty
2025 = twenty twenty-five

There is no single universal spoken style for every year, but this is the most common modern pattern.

7. Money: Prices, Cents, And Everyday Shopping English

Money numbers are everywhere: stores, restaurants, bills, tickets, and online shopping carts that somehow grow when nobody is looking.

Money Expression	Pronunciation Help	Meaning	Example Sentence	Learner Note
$1.00	one dollar	1 dollar	This notebook costs one dollar.	In speech, people usually say the amount without “dollars” if it is clear.
$5.25	five twenty-five	5 dollars and 25 cents	The coffee is five twenty-five.	Very common in American English.
$12	twelve dollars	12 dollars	The shirt is twelve dollars.	Use plural dollars after numbers above 1.
50¢	fifty cents	50 cents	I have fifty cents in my pocket.	“Cents” is plural.
$100	a hundred dollars	100 dollars	The repair costs a hundred dollars.	A hundred sounds natural.

Money speech tip: In everyday American English, people often leave out “dollars” when the context is obvious.

$4.99 = four ninety-nine
$8.50 = eight fifty
$120 = one hundred twenty or a hundred twenty

Important note: In stores, $4.99 is usually said as four ninety-nine, not four point nine nine.

8. Time And Clock Expressions

Numbers are also central to telling time. English uses a few common patterns.

Time	How To Say It	Meaning	Example Sentence	Learner Note
6:00	six o’clock	exactly 6:00	The meeting starts at six o’clock.	Use “o’clock” only for exact hours.
6:15	six fifteen	6:15	We left at six fifteen.	Common in American English.
6:30	six thirty / half past six	6:30	Lunch is at six thirty.	“Half past” is more common in British English.
6:45	six forty-five / quarter to seven	6:45	The train leaves at quarter to seven.	“Quarter to” and “quarter past” are common in spoken English.

Quick rule: In American English, people often use the digital style: seven ten, eight forty-five, nine oh five.

7:05 = seven oh five
8:10 = eight ten
9:00 = nine o’clock

10. Numbers With Common Grammar Patterns

Numbers do not just sit there looking numeric. They often control grammar too.

Pattern	Meaning	Example	Learner Note
number + plural noun	basic counting pattern	three apples, ten students	Use plural nouns after numbers bigger than one.
the + ordinal	specific position	the first page, the second floor	Very common in instructions and descriptions.

Age note: For people, English often uses:

He is thirty-two.
My son is five.

That last one may sound short, but it is completely normal.

11. Common Mistakes And Fixes

Numbers in English are simple once you learn the patterns. Cardinal for counting, ordinal for order, and the rest for real life. Which, sadly, does not stop numbers from showing up everywhere.

Yak Takeaway: Learn the pattern once, then use it everywhere—shopping, dates, time, money, and everything else that insists on being counted.
