Simplify: 36÷{12-(3+6)*5}​

12/11

Step-by-step 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.
