Simplify the following expression.

3(12 + 12) ÷ (14 – 8)

3(12 + 12) ÷ (14 – 8)

First, we simplify the expression inside the brackets:

3(24) ÷ (14 – 8)

Next, we simplify the expression inside the parentheses:

3(24) ÷ 6

Now, we perform multiplication first:

72 ÷ 6

Finally, we perform division:

12

Therefore, the simplified expression is 12.

To simplify the expression 3(12 + 12) ÷ (14 - 8), follow the order of operations (PEMDAS/BODMAS) which states that we first simplify within parentheses, then perform any multiplications or divisions from left to right, and finally any additions or subtractions from left to right.

Step 1: Simplify within parentheses:
12 + 12 = 24

Step 2: Substitute the simplified expression back into the original expression:
3(24) ÷ (14 - 8)

Step 3: Simplify the multiplication:
3 * 24 = 72

Step 4: Simplify within parentheses:
14 - 8 = 6

Step 5: Divide:
72 ÷ 6 = 12

Therefore, the simplified expression is 12.
