Make 11 out of 7, 7, 9, and 9

At least one solution contains the following operations, used exactly once each, but not necessarily in the order given:

Do we need to use all the operators?
If not is it

(7*(7+9))/9 ?

The Ans is : ((9-7)*9)-7

I think you people got misunderstood with the question.

You have to use all the digits, in any order with the help of operator provided (any).
