Answer 2

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

P: Parentheses first E: Exponents (none in this case) MD/BODMAS: Multiplication and Division from left to right AS/BODMAS: Addition and Subtraction from left to right

So, the expression is: 8.6 - (45 - 6.2) / 0.31

Let's simplify it step by step:

Step 1: Calculate the value inside the parentheses: 45 - 6.2 = 38.8

Step 2: Divide the result by 0.31: 38.8 / 0.31 = 125.16129032258 (approximately)

Step 3: Subtract the above result from 8.6: 8.6 - 125.16129032258 ≈ -116.56129032258

The answer to the expression is approximately -116.56.
