Answer 3

Let's break down the expression step by step:

1. 19 × 27: Multiply 19 by 27. Result: 513

2. 8 × 5: Multiply 8 by 5. Result: 40

3. (513/19) = 27: Divide 513 by 19. Result: 27

4. 3 ÷ 10: Divide 3 by 10. Result: 0.3

5. 15 ÷ 7: Divide 15 by 7. Result: 2.14285714286 (rounded to 11 decimal places)

6. 10 ÷ 3: Divide 10 by 3. Result: 3.33333333333 (rounded to 11 decimal places)

7. 7 ÷ 15: Divide 7 by 15. Result: 0.46666666667 (rounded to 11 decimal places)

Now, let's put it all together:

(19 × 27) + (8 × 5) ÷ (19) = 27 + 40 ÷ 19 ≈ 27 + 2.10526315789 (rounded to 11 decimal places) ≈ 29.1052631579 (rounded to 11 decimal places)

(3 ÷ 10) × (15 ÷ 7) × (10 ÷ 3) ÷ (7 ÷ 15) ≈ 0.3 × 2.14285714286 × 3.33333333333 ÷ 0.46666666667 ≈ 1.94285714286 (rounded to 11 decimal places)

So the final simplified expression is approximately:

29.1052631579 ≈ 1.94285714286
