Answer 3

Let's solve this equation step by step:

1. First, calculate the expression inside the parentheses: 321 - 320 = 1

2. Now, let's divide 7 by 3: 7 / 3 = 2.33333 (approximately)

3. Next, calculate the multiplication: 392 × 7 = 2744

4. Finally, put it all together: 2744 + 2.33333(1) - 9

Now, calculate the result:

2744 + 2.33333(1) - 9 ≈ 2744 + 2.33333 - 9 ≈ 2746.33333 - 9 ≈ 2737.33333

So, 392×7+7:3(321-320)-9 is approximately equal to 2737.33333.
