Answer 2

Let's simplify the expression step by step:

First, let's simplify the numerator: -2b × (-3) × 125 / 5 × (-75b) - 88ab × 9.3 / 3.1 × (-6.6) × (-4ab)

= 6b × 125 / 5 × (-75b) - 88ab × 9.3 / 3.1 × 6.6 × (-4ab) (negatives cancel)

= 750b² - 5149.44ab²

Now, let's simplify the denominator: -9 × 2.4 × 7.2 / -3 × 1.8 × 3.6 × 12 × (-8.5) × (-0.23) / 5 × (-2.3) × (-0.6)

= 15.552 / 5.832 × 275.76 / 19.56

= 2.67 × 14.1

= 37.647

Finally, let's divide the numerator by the denominator: (750b² - 5149.44ab²) / 37.647

So, the simplified expression is: (750b² - 5149.44ab²) / 37.647
