.

Have you seen,  at least once in your life,  a Math problem in a textbook with no question ?

I am sure,  you have not seen it never and nowhere.  Due to the simple reason,  that such problems  DO  NOT  EXIST.

Then why do you post an expression with no question to this forum ?

Please do not do it  NEVER  AGAIN.


~~~~~~~~~~~~~~~~

If you need simplify the expression,  say it  EXPLICITLY  in your post :  "Please simplify".

And if you really need simplify it,  then reduce the common factor of  "3"  in the numerator and in the denominator.


Happy reducing !

I think you meant either

(1) Simplify

9%2F%283d-3%29

Factor the denominator by taking out 3

9%2F%283%28d-1%29%29

Divide top and bottom by 3:

3%2F%28d-1%29

or you meant

(2) Write as one fraction by combining the terms:

9%2F%283d%29-3

In the first term, divide numerator and denominator by 3:

3%2Fd-3

Write 3 as 3%2F1

3%2Fd-3%2F1

The LCD is d.  To make the 1 denominator become
the LCD, multiply it by 1 in the form %28d%29%2F%28d%29

3%2Fd-expr%283%2F1%29expr%28%28d%29%2F%28d%29%29

Multiply the numerators and denominators in the second fraction:

3%2Fd-%283d%29%2Fd

Combine the numerators over the common denominator:

%283-3d%29%2Fd

If you like you may factor 3 out of the numerator, but it
is not necessary:

%283%281-d%29%29%2Fd
