Proper use of numbers:


Is it necessary to use a comma when stating 4,000 in a literary piece? Or is 4000 acceptable?

How should this be stated? In her thirties, in her 30's or in her thirty's?

Ideally, we don't use an apostrophe to create a plural noun. In this respect, 30's and thirty's are incorrect. They should be 30s and thirties. The same rules of pluralization (adding "s" and "ies") apply.


How you write numbers is a matter of preference, but Grammar Book recommends using commas for figures that are four or more digits (e.g. 3,459 students). Hope it helps.
