Answer:
To simplify the expression, follow the order of operations (PEMDAS):
1. Evaluate the division operations:
- 5/4 = 1.25
- 8/7 = 1.14
2. Replace the division operations with their values:
6 - 1.25 * 6 - 1.14
3. Multiply 1.25 and 6:
6 - 7.5 - 1.14
4. Combine the constants:
6 - 8.64
5. Perform the subtraction:
-2.64
So, the simplified expression is -2.64.
