Date n Numbers

Date and Numbers in English

Dates
In English, we can say dates either with the day before the month, or the month before the day:
The first of January / January the first.
Remember to use ordinal numbers for dates in English.
(The first, the second, the third, the fourth, the fifth, the twenty-second, the thirty-first etc.)
Years
For years up until 2000, separate the four numbers into two pairs of two:
1965 = nineteen sixty-five
1871 = eighteen seventy-one
1999 = nineteen ninety-nine
For this decade, you need to say "two thousand and —-" when speaking British English:
2001 = two thousand and one
2009 = two thousand and nine
Large numbers
Divide the number into units of hundreds and thousands:
400,000 = four hundred thousand (no s plural)
If the number includes a smaller number, use "and" in British English:
450,000 = four hundred and fifty thousand
400,360 = four hundred thousand and three hundred and sixty
Fractions, ratios and percentages
½ = one half
1/3 = one third
¼ = one quarter
1/5 = one fifth
1/ 6 = one sixth etc
3/5 = three fifths
1.5% = one point five percent
0.3% = nought / zero point three percent
2:1 = two to one
Saying 0
Depending on the context, we can pronounce zero in different ways:
2-0 (football) = Two nil
30 – 0 (tennis) = Thirty love
604 7721 (phone number) = six oh four…
0.4 (a number) = nought point four / zero point four
0C (temperature) = zero degrees
Talking about calculations in English
+ (plus)
2 + 1 = 3 (two plus one equals three)
- (minus / take away)
5 – 3 = 2 (five minus three equals two / five take away three equals two)
x (multiplied by / times)
2 x 3 = 6 (two multiplied by three equals six / two times three equals six)
/ (divided by)
6 / 3 = 2 (six divided by three equals two)

Expressing numbers in English

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’.
Two hundred NOT two hundreds
NOTE: British English takes 'and' between 'hundred and ...' American English omits 'and'. In the examples below, this is represented: (AND)
Hundreds
350 – three hundred (AND) fifty 425 – four hundred (AND) twenty five
Thousands
15,560 – fifteen thousand five hundred (AND) sixty 786,450 – seven hundred (AND) six thousand four hundred (AND) fifty
Millions
2,450,000 – two million four hundred (AND) fifty thousands 234,700,000 – two hundred (AND) thirty-four million seven hundred thousand
Speaking About Numbers
Numbers are read in the following manner in English:
million, thousand, hundred
Example:
2,350,400 => two million three hundred (AND) fifty thousand four hundred
NOTE - Remember: Use ‘and’ only between hundreds in British English. American English leaves the ‘and’ out.
Decimals
Read decimals as the given number point XYZ
2.36=>two point three six
Percentages
Read percentages as the number followed by ‘percent’
37%=>thirty seven percent
Fractions
Read the top number as a cardinal number, followed by the ordinal number + ‘s’
3/8=>three eighths
NOTE: ¼ =>one quarter, 2/3 => two thirds, ½ one half
Expressions
Here are the descriptive names of a number of important numerical expressions:
Speed 100 mph (miles per hour)
Weight 80 kg (kilograms) OR 42 lbs (pounds)
telephone number 0171 895 7056

Expressing Numbers in English

:: If a number is in the range 21 to 99, and the second digit is not zero, we should write the number as two words separated by a hyphen:

25   twenty-five

57   fifty-seven

89   eighty-nine

:: Numbers over 100 are generally written in figures. However if you want to say them aloud or want to write them in words rather than figures you put 'and' in front of the number expressed by the last two figures. For example:

203      two hundred and three             (AmE: two hundred three)

622      six hundred and twenty-two     (AmE: six hundred twenty-two)

:: Numbers between 1000 and 1,000,000 is usually said or written in words as:

1,803    one thousand, eight hundred and three            (AmE: one thousand, eight hundred three)

1,963    one thousand, nine hundred and sixty-three     (AmE: one thousand, nine hundred sixty-three)

2,840    two thousand, eight hundred and forty            (AmE: two thousand, eight hundred forty)

Four-figure numbers ending in 00 can also be said or written as a number of hundreds. For example, 1800 can be said or written as "eighteen hundred"

:: If the number 1963 is being used to identify something, it is said as "one nine six three". We always say each figure separately like this with telephone numbers. If a telephone number contains a double number, we use the word "double":

561 6603    five six one [pause] double six 'oh' three  (AmE: five six one [pause] six six 'oh' three)

:: Saying years. We normally say a year in two parts. In the case of years ending in "00", we say the second part in "hundred":

1058   ten fifty-eight

1706   seventeen hundred and six (or 'seventeen oh six')

1865   eighteen sixty-five

1900   nineteen hundred

There are two ways of saying years ending in "01" to "09" before 2000. For example: "1901" can be said as "nineteen oh one" or "nineteen hundred and one". The year 2000 is read "two thousand", 2006 "two thousand and six" (AmE: two thousand six). Post-2010 dates are often said as normal (2010 would be "twenty ten").

:: Flight numbers. We pronounce a flight number in two parts or digit-by-digit. For example:

110      one ten (or 'one one oh')

1248    twelve forty-eight

2503    twenty-five oh three

3050    three oh five oh (or 'three zero five zero', 'thirty fifty')


:: Expressing millions.

1,412,605        one million four hundred (and) twelve thousand six hundred (and) five

2,760,300        two million seven hundred (and) sixty thousand three hundred

Remember: The British use 'and' before tens and ones but the Americans usually leave the 'and' out.

Ways of expressing the number 0

0 = nil in football and other sports, for scores of 0 (AmE: zero or nothing)

0 = love in tennis

0 = zero in temperatures to refer to freezing point (0° Celsius, 0° Fahrenheit)

0 = nought in mathematics (AmE: zero)

0 = oh for telephone numbers

0 = oh (or zero) for flight numbers

Notes:

1. We use zero to express some numerical values such as temperatures, taxes, and interest rates.

2. We can pronounce "0" like the letter "o", when we are reading out numbers figure by figure (e. g. telephone number, flight number, credit card number, etc.)

Fractional numbers /дроби/

½	a half	0.5	British English nought point five American English zero point five
2½	two and a half	2.5	two point five
¼	a quarter	0.25	British English nought point two five American English zero point two five
¾	three quarters American English also three fourths	0.75	British English nought point seven five American English zero point seven five

Writing full stops and commas in numbers

Use a full stop (.) to separate the main part of a number from the decimal part. 3.062 means 'three point nought six two'.

Say point to refer to the full stop. You can use a comma (,) in large numbers to separate the hundreds, thousands, and millions. 3,062 means 'three thousand and sixty-two'. In British English, spaces are sometimes used instead of commas (3 062).

Remember: Speakers of some other languages use (,) and (.) in the opposite way - the commas for the decimals and the points for thousands, millions, etc.
