Answer 2

Let's simplify the given expressions:

1. (5/6) * (-8) * (3/5) Multiplying the numerators and denominators, we have: (5 * -8 * 3) / (6 * 5) = (-40) / 6 = -20/3

2. (1 1/2) * (-5) * (2/3) First, convert the mixed number 1 1/2 to an improper fraction: 1 1/2 = (2/2 + 1/2) = 3/2 Multiplying the numerators and denominators, we have: (3/2) * (-5) * (2/3) = (3 * -5 * 2) / (2 * 3) = (-30) / 6 = -5

3. (-1 3/7) * (-9) * (-7/10) First, convert the mixed number -1 3/7 to an improper fraction: -1 3/7 = (-7/7 - 3/7) = -10/7 Multiplying the numerators and denominators, we have: (-10/7) * (-9) * (-7/10) = (-10 * -9 * -7) / (7 * 10) = (-630) / 70 = -9

So, the simplified expressions are:

1. (5/6) * (-8) * (3/5) = -20/3
2. (1 1/2) * (-5) * (2/3) = -5
3. (-1 3/7) * (-9) * (-7/10) = -9
