How to write 45 in words
The number 45 is written “forty-five” in British English. The hyphen in forty-five is not optional – every compound number from twenty-one to ninety-nine is hyphenated.
45 is one of the basic number words that every larger number is built from, so it has to be learned rather than constructed – but remember the hyphen between the tens and the units.
In running text the number is normally lowercase: “the fee is forty-five pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Forty-Five. Formal documents often give both forms together, for example “forty-five (45)”, so that a reader can check one against the other.
