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 apply this to the given expression:

0.25 * (12.8 * 1.5 - 7.98)

Step 1: Calculate what is inside the parentheses first.

12.8 * 1.5 = 19.2 19.2 - 7.98 = 11.22

Step 2: Now, multiply the result from the parentheses by 0.25.

0.25 * 11.22 = 2.805

So, the final answer is 2.805.
