Hundreds, Thousands and Millions

  • The hundreds and tens are usually separated by 'and' (though in American English the 'and' is often omitted) e.g. one hundred and twenty-four
  • You can say 'a hundred' or 'one hundred', 'a thousand' or 'one thousand', but only when at the start of a number e.g. a hundred and fifty / one hundred and fifty (150)
  • If it is not at the beginning of the number then 'one' is used e.g. four thousand, one hundred (4,100), NOT four thousand, a hundred
100 a/one hundred
124 one hundred and twenty-four
200 two hundred
1000 a/one thousand
1460 one thousand, four hundred and sixty
2001 two thousand and one
1,000,000 a/one million
