According to the question,

7−x/ 9−x= 11−x/ 15−x

Now, check through options
Clearly, putting x = 3,

Each ratio = 2/3

Let the number to be subtracted  be x

Now we will solve this:

7 − x/9 − x  =   11 − x /15 − x

Now we will check this answer by putting the value of x as 3

So the answer to this question is 2/3
