The correct way to write "and/or" together in a sentence [closed]
You'd be hard pressed to find a style guide that doesn't admonish you to drop “and/or” and choose either “and” or “or.”
In writing either and or or is usually adequate.
If a greater distinction is needed, another phrasing is available
: X or Y, or both.

And/or
ELU: The difference between "and" and "and/or"
It is more common in technical,business,and legal writing.
There is no correct way; it depends on what style guide you are using.
However, at least in AmE, and/or is the vastly more common construction. If in doubt, I would choose and/or.
