answer:

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

1. Start with the innermost parentheses:

-9 - 6 = -15

3 - 3 × 4 = 3 - 12 = -9

32 - 8 × 9 = 32 - 72 = -40

-5 × (-1 + 7) = -5 × 6 = -30

2. Now, substitute these values back into the expression:

60 / -15 - 54 / -9 + (-40) / -30

3. Simplify each division operation:

60 / -15 = -4

54 / -9 = -6

-40 / -30 = 4/3 or 1.33 (rounded to two decimal places)

4. Substitute the simplified values back into the expression:

-4 - 6 + 1.33

5. Perform the remaining addition and subtraction:

-4 - 6 + 1.33 = -9.67

Therefore, the value of the given expression is approximately -9.67.
