Answer 2

Let's break down the expression step by step:

1. Start with the multiplication inside the parentheses: (5 5/28 - 5 1/3 * 1.25 - 1 16/21)

2. Convert mixed numbers to improper fractions: (5 5/28 - (16/3) * 1.25 - (37/21))

3. Perform the multiplication: (5 5/28 - (16/3 * 1.25) - (37/21))

4. Calculate 16/3 * 1.25: (5 5/28 - 20/3 - (37/21))

5. Find a common denominator for 28 and 3, which is 84: (5 * 84/28 - 20 * 28/3 - 37/21)

6. Simplify the fractions: (420/28 - 560/3 - 37/21)

7. Now, let's calculate the values: (15 - 186.6667 - 1.7619)

8. Subtract 15 from the result: -171.4286 - 1.7619

9. Subtract the two results: -173.1905

10. Finally, divide by -1.5: (-173.1905 / -1.5) ≈ 115.46 (rounded to two decimal places)

So, the final result is approximately 115.46.
