(156-96 :12):(4:2)=

Let's break down the expression step by step. 1. First, we solve the inner part: \( 156 - 96 = 60 \) 2. Next, divide by 12: \( 60 \div 12 = 5 \) 3. Now, we have the expression: \( 5 : (4 : 2) \) 4. Solve \( 4 : 2 \): \( 4 \div 2 = 2 \) 5. Now, we simplify the expression \( 5 : 2 \): \( 5 \div 2 = 2.5 \) Thus, the final result of the original expression \( (156 - 96 : 12) : (4 : 2) \) is \( 2.5 \).
