The number 100 is written as "one hundred", but in general, sometimes people can say "a hundred".

The way numbers are written and spoken differs between American English and other forms of English, such as British English and Australian English, as follows.

American English

To write a whole number from 100 to 999 in American English:

  • First write how many hundreds.
  • Then write the word "hundred".
  • Then write the name of the two-digit number after the digit in the hundreds place.

In standard, written, American English, the word "and" is not in the word-name of any whole number even though many speakers insert it.

Examples:

  • 101: one hundred one
  • 102: one hundred two
  • 175: one hundred seventy-five
  • 200: two hundred
  • 300: three hundred
  • 400: four hundred
  • 512: five hundred twelve
  • 513: five hundred thirteen
  • 600: six hundred
  • 987: nine hundred eighty-seven

British and Commonwealth English

  • First write how many hundreds.
  • Then write the words "hundred and".
