1. Reading Basic Numbers
Before diving into the more complex numbers, let’s first understand how to read basic numbers in English.
These are numbers from 1 to 10, and they are the building blocks for larger numbers.
Here are the first few numbers and how to say them:
- 1 – One
- 2 – Two
- 3 – Three
- 4 – Four
- 5 – Five
- 6 – Six
- 7 – Seven
- 8 – Eight
- 9 – Nine
- 10 – Ten
When reading larger numbers, you build them from these basic numbers.
2. Reading Big Numbers
Big numbers can seem scary, but once you understand the structure, it’s easy!
In English, we group numbers into thousands, millions, billions, and so on.
Here’s how to read big numbers:
Hundreds:
- 100 – One hundred
- 200 – Two hundred
- 350 – Three hundred fifty
- 999 – Nine hundred ninety-nine
Thousands:
- 1,000 – One thousand
- 5,000 – Five thousand
- 10,000 – Ten thousand

3. Reading Decimals
Decimals are numbers that have a part after a decimal point. In English, we say each digit after the decimal point as a separate number.
Here’s how to read decimals:
- 0.1 – Zero point one
- 1.25 – One point two five
- 3.14159 – Three point one four one five nine (this is Pi)
- 0.75 – Zero point seven five
- 8.9 – Eight point nine
Example Sentences:
- My phone number is 123.45 – One two three point four five.
- The price of the book is 19.99 – Nineteen point ninety-nine.
4. Reading Fractions
Fractions are another important part of numbers. A fraction is a way to express a part of a whole.
Here’s how to read fractions in English:
- 1/2 – One-half

- 1/4 – One-fourth or one-quarter
- 2/3 – Two-thirds
- 3/4 – Three-fourths or three-quarters
- 5/8 – Five-eighths
- 7/10 – Seven-tenths
Example Sentences:
- I ate 1/2 of the pizza – I ate one-half of the pizza.
- The cake is divided into 3/4 – The cake is divided into three-fourths.
5. Reading Dates
Reading dates in English can vary depending on where you are.
In most English-speaking countries, we use the format day/month/year or month/day/year.
Here’s how to read dates:
Days of the Month:
- 1st – First
- 2nd – Second
- 3rd – Third
- 21st – Twenty-first
- 22nd – Twenty-second
- 30th – Thirtieth
- 31st – Thirty-first
Months of the Year:

- February – February
- March – March
- April – April
- May – May
- June – June
- July – July
- August – August
- September – September
- October – October
- November – November
- December – December
How to Read Dates:
- 1st January – First of January
- 25th December – Twenty-fifth of December
- 12/11/2024 – Twelfth of November, twenty twenty-four (day/month/year format)
- 11/12/2024 – Eleventh of December, twenty twenty-four (month/day/year format)
6. Reading Phone Numbers
Phone numbers are often read digit by digit, especially in countries like the United States and the UK.
Here’s how to read phone numbers:
- 123-456-7890 – One two three, four five six, seven eight nine zero
- 555-1234 – Five five five, one two three four
If the phone number has an area code (like many numbers in the US), you usually say that first:
- (800) 555-1234 – Eight hundred, five five five, one two three four
7. Reading Ordinal Numbers
Ordinal numbers show the position or order of something. For example, first, second, third, and so on.
Here’s how to read them:
- 1st – First
- 2nd – Second
- 3rd – Third
- 4th – Fourth
- 5th – Fifth
- 10th – Tenth
- 21st – Twenty-first
- 100th – One hundredth
Example Sentences:
- He finished 1st in the race – He finished first in the race.
- My birthday is on 5th May – My birthday is on the fifth of May.
8. Reading Large Numbers: Tips and Tricks
Reading large numbers can sometimes be overwhelming, but here are some tips that can help you:
- Break it down: If the number is too large, break it into smaller parts. For example, 1,234,567 becomes One million, two hundred thirty-four thousand, five hundred sixty-seven.
- Understand the pattern: After a thousand, you get a million, then a billion, trillion, etc. The pattern is predictable.
- Practice regularly: Practice reading big numbers out loud so you become comfortable.
9. How to Read Percentages
Percentages are also an important part of reading numbers in English. To read percentages, you simply say the number followed by “percent.”
Here’s how:
- 50% – Fifty percent
- 12.5% – Twelve point five percent
- 100% – One hundred percent
Example Sentences:
- The company’s profit increased by 20% – The company’s profit increased by twenty percent.
- 45% of students passed the exam – Forty-five percent of students passed the exam.
10. Summary of Key Points
- Big Numbers: Break them into parts (thousands, millions, etc.).
- Decimals: Say each digit after the decimal point.
- Fractions: Say the numerator (top number) and denominator (bottom number) separately.
- Dates: Learn the day and month names and practice different date formats.
- Phone Numbers: Read each digit individually and use the area code first.
- Ordinals: Use “st,” “nd,” “rd,” and “th” to show position or order.
