Here we convert the cardinal number five hundred nine (509) to an
ordinal number. This is useful if you want to use the number 509 as an
adjective when you speak or write it.
There are two ways of writing 509 as an ordinal number, either with letters
and numbers or just letters as follows:
509th
five hundred ninth
When would you be using the ordinal instead of the cardinal version of 509
you ask?
You use 509 (cardinal) if you are describing how many of something, and you use 509th (ordinal) if you
are describing a position or rank of something.
Like we mentioned above, remember to use the ordinal version of 509 when
509 is used as an adjective.
