How to read 3. Rules for reading numbers, dates and mathematical expressions in English. Rules for the formation of numbers in English

What a new English learner cannot do without? What should your child learn for school? Without which you can't even tell what time it is now? Of course, no numbers. It is quite easy to learn numbers in English. You can memorize them with the help of interesting color pictures, you can sing like a song, you can memorize them like a tongue twister - space for imagination and creativity!

How to name numbers in English

Let's list the main numbers in English:

  • 0 - zero - zero;
  • 1 - one - one;
  • 2 - two - two;
  • 3 - three - three;
  • 4 - four - four;
  • 5 - five - five;
  • 6 - six - six;
  • 7 - seven - seven;
  • 8 - eight - eight;
  • 9 - nine - nine.

The following numbers do not lend themselves to the general rules of education:

  • 10 - ten - ten;
  • 11 - eleven - eleven;
  • 12 - twelve - twelve;
  • 100 - hundred - one hundred;
  • 1000 - thousand - thousand.

How to pronounce them correctly in English?

You can correctly pronounce numbers, and all other words of the English language, only if you know the transcription. Transcription is a special recording of a word the way it is pronounced (for example, the Russian word "draw" can be transcribed as [risavatsa]). And learning English numbers with transcription is much easier than without it.

This is how English numbers are read:

  • 0 - 🔊 Play zero - [‘ziərəu];
  • 1 - 🔊 Listen one -;
  • 2 - 🔊 Play two -;
  • 3 - 🔊 Listen three - [θri:];
  • 4 - 🔊 Listen four -;
  • 5 - 🔊 Listen five -;
  • 6 - 🔊 Listen to six. -;
  • 7 - 🔊 Listen seven - [‘sev (ə) n];
  • 8 - 🔊 Listen eight -;
  • 9 - 🔊 Listen nine -;
  • 10 - 🔊 Listen ten -;
  • 11 - 🔊 Listen eleven -;
  • 12 - 🔊 Listen twelve -;
  • 100 - 🔊 Listen hundred -;
  • 1000 - 🔊 Listen thousand - [θʌuzend].

But what if you don't know how the transcription is read? For those who are just going to learn English from scratch, numbers with Russian transcription are very useful:

  • 0 - zero - [zirou];
  • 1 - one - [yuan];
  • 2 - two - [that];
  • 3 - three - [sri];
  • 4 - four - [pho];
  • 5 - five - [five];
  • 6 - six - [sixx];
  • 7 - seven - [seven];
  • 8 - eight - [yut];
  • 9 - nine - [nine];
  • 10 - ten - [ten];
  • 11 - eleven - [ileven];
  • 12 - twelve - [twelve];
  • 100 - hundred - [handred];
  • 1000 - thousand - [southend].

All possible numbers, the largest imaginable, are just combinations of nine numbers, from zero to nine. The numbers are formed according to special rules.

Rules for the formation of numbers in English

Generally, numbers in English can be divided into:
simple;
derivatives;
composite.


Understanding which number is which is very simple. Simple consist of one word (for example: five, nine, thousand). Derivatives consist of one word, but have the suffixes -teen (from 13 to 19) or -ty (tens from 20 to 90). Composite however, as their name implies, they consist of several numbers.

How to form derivative numbers?

To form derivatives from 13 to 19, take a number from 3 to 9 and add the suffix -teen to it. Some letters may change at the same time! Be careful!

13 - three + teen \u003d thirteen;
14 - four + teen \u003d fourteen;
15 - five + teen \u003d fifteen;
16 - six + teen \u003d sixteen;
17 - seven + teen \u003d seventeen;
18 - eight + teen \u003d eighteen;
19 - nine + teen \u003d nineteen.

The stress in these numbers will fall on the suffix. Numbers are read in accordance with the transcription of the first parts (for example: fifteen - [fifin], eighteen - [eutin]).

To form derivative numbers from 20 to 90, take a number from 2 to 9 and add the -ty suffix to it.

20 - two + ty \u003d twenty;
30 - three + ty \u003d thirty;
40 - four + ty \u003d forty;
50 - five + ty \u003d fifty;
60 - six + ty \u003d sixty;
70 - seven + ty \u003d seventy;
80 - eight + ty \u003d eighty;
90 –nine + ty \u003d ninety.

The stress in these numbers will fall on the root. They are read in the same way as the first parts: (for example: sixty - [sixty], forty - [foti]).

How to form compound numbers?

Composite numbers are formed using tens + ones (if the number is less than one hundred), hundreds + tens + ones (if the number is less than one thousand), etc.

For example, suppose you want to form the number "twenty-one". You need to write two words: "twenty" and "one". Thus, twenty-one is twenty-one! In this case, two-digit numbers are written with a hyphen.
Similarly, you can form any numbers up to a hundred:

Fifty-three - fifty + three \u003d fifty-three.
Forty nine - forty + nine \u003d forty-nine.
Seventy two - seventy + two \u003d seventy-two.
Thirty-six - thirty + six \u003d thirty-six.
Ninety nine - ninety + nine \u003d ninety-nine.

To form any number up to a thousand, you must specify the number of hundreds + tens + units, and after the number of hundreds is written and (British English), and then a two-digit number separated by a hyphen:

One hundred and twenty-one.
Five hundred forty-three - five hundred and forty-three.
Two hundred and two.
Three hundred fifty-eight - three hundred and fifty-eight.
Four hundred - four hundred.

Likewise with large numbers. They are pronounced in the same way as their parts.

That's all - now you know English numbers, you can read them correctly and make numbers out of them. Although it is quite difficult to remember all the numbers and the rules for their formation at once, this should not repel you. Look for different tongue twisters, rhymes, songs, watch training videos - in general, in training, as in war, all means are good! Good luck learning English!

It so happens that seeing a fraction in a text or article, we do not know how to read it correctly. And if you are going to study Business English and use it in your professional activities, then you should not doubt the correctness of the data you have provided. And in everyday life you can't do without fractions. In this article, we will learn the rules for reading different types of fractional numbers in English, remembering which, you will always be sure that you are speaking correctly.

Fractions are of two types: ordinary, which are written with a dash (common fractions or simple fractions) and decimal, which have a period (decimals).

Ordinary fractions

Reading simple fractions is quite simple, and very similar to how we read them in Russian. A common fraction has two components: the numerator (Number above the line) and denominator (number below the line). The upper number (numerator) is read as cardinal number (How much?), And the bottom number (denominator) is as ordinal (Which is in order?). In this case, the numerator one can be read as the article a:

1/3 - one third / a third
1/7 - one seventh / a seventh
1 / 9- one ninth / a ninth

If the numerator is greater than one, then the denominator acquires a plural ending:

2/3 - two thirds
3/5 - three fifths

Remember that half when reading fractions is half, and a quarter can be read as (a / one) quarter or (a / one) fourth:

1/2 - one half / a half NOT one second
1/4 - one quarter / a quarter / one fourth
3/4 - three quarters / three fourths

If the fraction contains an integer ( whole), then it is associated with fractional using the word and:

1 1/2 - one and a half
3 2/3 - three and two thirds
2 1/4 - two and a quarter / two and a forth

Reading decimals

First of all, it is important to remember that English decimal fractions use a full stop, not a comma. In English decimal fractions, we do not say the words: tenths, hundredths, thousandths, but simply name the numbers. And when reading decimal fractions, the word point is said and each digit is called separately:

2.25 - two point twenty five
1.4 - one point four
6.785 - six point seven eight five

If there is no integer, but there are numbers only after the dot, then they say noughtor zero(in American English), or missing zero altogether in both speech and writing:

0.2 - nought (zero) point two / point two
0.75 - nought (zero) point seven five / point seven five
0.03 - nought (zero) point nought three / point nought three

Interest

Often percentages are indicated in decimal fractions: per cent (percent AmE). The word per cent is used in the singular:

2.2% - two point two per cent
3.5% - three point five per cent
50% - fifty per cent
99% - ninety-nine per cent

The use of the word percents is possible only in relation to the school topic "Percents", but cannot be used with specific numbers.

The rules for reading numbers in English are in many ways similar to reading numbers in Russian. So, when pronouncing three-digit numbers, they first call the hundreds, then ten and ones.

Seven hundred and ninety three

seven hundred ninety three

The example shows that reading numbers in english after the rank of hundreds is accompanied by the conjunction and. Its presence is optional, so and can be omitted. Although, in practice, this union is convenient. Especially for those who first think in their native language, and then give out a phrase in English. Pronouncing the word and leaves time to remember how to pronounce this or that part of the number.

When sounding numbers in which there are four or more digits, the reading of the number begins with the most senior digits, and ends with the digits of hundreds-tens-units. The numbers are pronounced in threes. Each three digits is voiced according to the rules for reading three-digit numbers, only at the end they add the words: "billion", "million", "thousand" and so on. Let's give an example:

one trillion, three hundred and twenty-nine billion, hundred seven and eighty million, one hundred and ninety-one thousand, four hundred and twenty-five

one trillion three hundred twenty nine billion seven hundred eighty million one hundred ninety one thousand four hundred twenty five

It is necessary to pay attention to the fact that such names of categories as: "hundreds", "thousands", "millions", "billions" and so on, in English are always pronounced in the singular, respectively, they do not have the ending -s.

Six hundred and fifty four

six hundred fifty four

When reading fractional numbers, the integer part is pronounced first, and then the fractional remainder. Reading the fractional part can be done in several different ways. Let's imagine them using the example of the number "seventeen point twenty one thousandth":

seventeen point oh twenty-one, seventeen point zero twenty-one, seventeen and twenty-one thousandths

This example shows that in the fractional part, you can pronounce each digit separately, having previously used the word point, or you can voice the fractional part as a whole.

Let's start our consideration of dates in English with the rules for pronouncing the year. If the numerical designation of the year does not exceed three digits, then the year is pronounced according to the usual rules for reading numbers. To clarify which era the date belongs to, after pronouncing the year, add BC or AD. BC means "BC", AD - "AD".

In the 1st century BC several kingdoms located in modern-day Myanmar traded with India and China.

In the first century BC, several kingdoms located in the territory of present-day Myanmar traded with India and China.

A year with a four-digit number is divided into two parts: the first and last two digits are voiced separately from each other, as two two-digit numbers, for example:

In thirteen sixty-seven ...

In one thousand three hundred and sixty-seven ...

However, if the year is the beginning of the new millennium, for example: two thousandth, then it is voiced as a whole.

Two thousand fifth

two thousand and five

For example, in a BBC report, you can hear dates pronounced:

In 2012 - In two thousand and twelve (2000 and 12)

By 2045 - By two thousand and forty five (2000 and 45) or - By twenty forty five (20, 45)

In the case when the month and day are indicated in the date along with the year, the date can be read in two different ways: starting with the month and starting with the day. Example:

on April 26th, 1992

on the 2nd of August, 1873

2nd August 1873
