[((7 * 20))/(11) - 9]
(2)/(8) =
(41)/(44)

The given question can be expressed using the required parentheses if the final answer is known. But the problem can be expressed as:


[((7 * 20))/(11) - 9]
(2)/(8)

So that;


[(140)/(11) - 9]
(2)/(8)


[(140 - 99)/(11)]
(2)/(8)


(41)/(11) *
(2)/(8) =
(82)/(88)

=
(41)/(44)

Therefore, we have.


[((7 * 20))/(11) - 9]
(2)/(8) =
(41)/(44)
