How can I output rational numbers in properly formatted parentheses?

Question

I want to output this:

If I input it like that, the output removes the parentheses, leaving just:

What I tried:

"("<>ToString[TraditionalForm[15/2]]<>")"

But then the parentheses come out too small:

How can I retain proper size parentheses in the output?

Before you get many different solutions, you should perhaps specify more clearly what is your actual use case of this. Do you want to be able to copy&paste the output? Do you actually want to use this for more complicated expressions, or do you really want just one fraction in the output? — Domen

@Domen I need to convert it to a string and place in the overscript at a vertex in a graph. I accepted yours, it just repeats exactly the way it is in the input. — მამუკა ჯიბლაძე

@Syed Well thanks, but I cannot say I figure out how to use it straight away — მამუკა ჯიბლაძე

Here is a simple solution with boxes.

DisplayForm[RowBox[{"(", ToBoxes[15/2], ")"}]]

Since this is just for display purpose, why not simply use MaTeX?

e = 15/2; g = MaTeX["\\left(" <> ToString[TeXForm[e]] <> "\\right)", Magnification -> 2]; g

I am sure this can be also done uses "boxes" and such also. But I am not good with Boxes formatting.

One way would be:

ToString@TraditionalForm@MatrixForm[{15/2}]

that gives:
