How do you spell 90?
The cardinal number “90” is spelled ninety. As it is a determiner, ninety always precedes the noun it modifies (e.g., “a check for ninety dollars”). Ninety as an ordinal number is “ninetieth” (e.g., “this is the ninetieth anniversary of the city”).
Ninty is always wrong, and this common mistake likely arises from how other numbers are spelled. For example, it’s “forty,” not “fourty,” despite the word coming from “four.” However, in the case of “nine,” ninety is the correct spelling.

If you have trouble remembering how to spell ninety, remember that it comes from “nine.” Write “nine” and add the “ty” to the end.
An exception to this is when ninety starts a sentence. In that case, you want to write it out (e.g., “Ninety years ago …” instead of “90 years ago …”).
There may be different conventions in academic writing, journalism, or other types of writing that generally adhere to a style guide. When in doubt, check the relevant guide.
