Answer 2

Let's simplify each of the given expressions:

1. (-2/3) × (6/7) × (1/10):

To multiply fractions, we multiply the numerators together and the denominators together: (-2 × 6 × 1) / (3 × 7 × 10) = -12 / 210 = -2/35

2. (-6/7) × (-3/5) × (6/5):

Multiplying the numerators and denominators: (-6 × -3 × 6) / (7 × 5 × 5) = 108 / 175 = 108/175

3. (-24/36) × (-3/4) × (-2/9):

Multiplying the numerators and denominators: (-24 × -3 × -2) / (36 × 4 × 9) = -144 / 1296 = -1/9

4. (-2/3) × (5/6) × (-9/10):

Multiplying the numerators and denominators: (-2 × 5 × -9) / (3 × 6 × 10) = 90 / 180 = 1/2

5. (-1/3) × (-135) × (1/5):

Multiplying the numerators and denominators: (-1 × -135 × 1) / (3 × 1 × 5) = 135 / 15 = 9

6. (2/7) × (-21) × (-1/3):

Multiplying the numerators and denominators: (2 × -21 × -1) / (7 × 1 × 3) = 42 / 21 = 2

So, the simplified values of the given expressions are:

1. -2/35
2. 108/175
3. -1/9
4. 1/2
5. 9
6. 2
