I'm wondering what people do when it comes to writing numbers in a story? I typically spell out numbers <= 100, but also write numbers like one thousand as words rather than 1,000. I eventually settled on a rule that if I could write it out in three words or less, then I would do so. As a result, numbers like 500, 10,000, 1,000,000, etc. all get written out. I tend to include 'and' when writing numbers, so 350 would be three hundred and fifty, which is four words, so I wouldn't write it out. One of my reviewers recommended I write 350 as three hundred-fifty in a line of dialogue, hence this post.
Thanks
