Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

1. First, perform the division inside the parentheses: (54130 - 12,800) ÷ 2 = 42,330 ÷ 2 = 21,165

2. Next, divide the result by 30: 21,165 ÷ 30 ≈ 705.5

So, the value of the expression (54130 - 12,800 : 2) : 30 is approximately 705.5.
