Question not definitively clear as to intention.
I got $2/9 .color(white)(..)$ Have a look at the method. Particularly at the end.

Given: $[(30+6)-32] -: 9 xx 2$

Note that formatting star gives you $*$
Formatting a full stop gives you $.$

So the original question ends with 9 times 2 and not 9 point 2

There are two interpretations as to what the question proposer was after.

Intention 1: $[(30+6)-32] -: (9 xx 2)$

Intention 2: $((30+6)-32)/(9) xx 2$

$color(blue)("Assumption: Intention 1 is the case.")$

Write as

$(30+6-32)/(9xx2) = (6-2)/(9xx2) = 4/18$

$color(brown)("Divide top and bottom by 2 giving")$

$(4-:2)/(18-:2) =2/9$

How do you evaluate [(30 + 6) − 32] ÷ 9 * 2[(30 + 6) − 32] ÷ 9 * 2?
