Answer 2

To solve the given expression, let's break it down step by step:

1. Perform the operations inside the parentheses: 7 - 6 1/15 = 6 14/15

2. Subtract the result from step 1 from 5 7/8: 5 7/8 - 6 14/15

3. Convert the mixed numbers to improper fractions for easier calculation: 5 7/8 = (8 * 5 + 7) / 8 = 47/8 6 14/15 = (15 * 6 + 14) / 15 = 104/15

4. Subtract the improper fraction obtained in step 3 from the other improper fraction: (47/8) - (104/15)

5. Find a common denominator for the fractions (LCD) which is 120 (8 * 15): (47/8) * (15/15) - (104/15) * (8/8) (705/120) - (832/120)

6. Subtract the fractions: (705 - 832) / 120 (-127/120)

7. Next, add the fractions 4/25 and 5/6: (4/25) + (5/6)

8. Find a common denominator for the fractions (LCD) which is 150 (25 * 6): (4/25) * (6/6) + (5/6) * (25/25) (24/150) + (125/150)

9. Add the fractions: (24 + 125) / 150 (149/150)

So, the final result of the given expression is: (-127/120) + (149/150)
