Answer 2

To solve the expression, we'll simplify the given multiplication of fractions step by step:

(-2/19) × (-3/4) × (-9 1/2) × (7/20) × (-3/17) × (-8 2/21) × (-13/25) × (-5 10/13) × (2/3)

First, let's simplify the mixed numbers by converting them to improper fractions:

-9 1/2 = -(9 + 1/2) = -19/2 -8 2/21 = -(8 + 2/21) = -170/21 -5 10/13 = -(5 + 10/13) = -75/13

Now, we can multiply the fractions:

(-2/19) × (-3/4) × (-19/2) × (7/20) × (-3/17) × (-170/21) × (-13/25) × (-75/13) × (2/3)

Next, we can cancel out any common factors between the numerators and denominators. However, in this case, there are no common factors to cancel out.

Now, we can multiply the numerators together and multiply the denominators together:

(-2 × -3 × -19 × 7 × -3 × -170 × -13 × -75 × 2) / (19 × 4 × 2 × 20 × 17 × 21 × 25 × 13 × 3)

Simplifying further:

(180180 / 3990768000)

The fraction cannot be simplified any further, so the final answer is:

180180 / 3990768000
