Answer:
12/11
Explanation:
Any work inside parentheses must be done first.
Thus, start with (3 + 6); this equals 9. Then the original expression becomes
36÷{12-(9)*5}
Multiplication and division are done before addition and subtraction. Thus, the next stp is to multiply 9 and 5, obtaining 45, inside the parentheses. This results in
36÷{12-45}, or 36÷{33}, which leads to the answer 36/33, or 12/11.
