Answer 1

((23.79:7.8-6.8:17)•3.04-2.04)•0.85 = ((3,05-0,4)•1)•0,85= 3,05-0,4•0,85=3,05+0,34=3,39

Answer 2

To solve the expression ((23.79:7.8-6.8:17)•3.04-2.04)•0.85, you can follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction). Here's the step-by-step solution:

1. Start with the innermost parentheses/brackets: (23.79:7.8-6.8:17)

2. Perform the divisions first: (3.05 - 0.4)

3. Now, subtract the two results: 2.65

4. Next, multiply the result by 3.04: 2.65 * 3.04 = 8.052

5. Finally, subtract 2.04 from the result and then multiply it by 0.85: (8.052 - 2.04) * 0.85

6. Calculate the subtraction inside the parentheses: 6.012 * 0.85

7. Multiply the two numbers to get the final answer: 5.1102

So, the final result of the expression ((23.79:7.8-6.8:17)•3.04-2.04)•0.85 is approximately 5.1102.
