To simplify the given expressions, follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

Let's simplify each expression step by step:

Expression 1: - 2/3 ( C - 12 )

Step 1: Distribute the negative sign to both terms inside the parentheses:
-2/3 * C + (-2/3) * (-12)

Step 2: Simplify the multiplication:
(-2/3)C + (2/3) * 12

Step 3: Multiply the fractions and simplify further:
(-2/3)C + 24/3

Step 4: Simplify the fraction:
(-2/3)C + 8

Final answer: -2/3C + 8

Expression 2: - 8 ( t/2 + 6 )

Step 1: Distribute the negative sign to both terms inside the parentheses:
-8 * (t/2) + (-8) * 6

Step 2: Simplify the multiplication:
(-8/1) * (t/2) + (-8) * 6

Step 3: Simplify the fractions:
-4t + (-48)

Step 4: Simplify further:
-4t - 48

Final answer: -4t - 48

Remember, always follow the order of operations while simplifying expressions to ensure the correct answer.
