Answer 2

Let's calculate these two expressions step by step:

1. $-\frac{2}{3} \times \frac{6}{7} \times \frac{1}{10}$:

First, multiply the fractions from left to right:

$-\frac{2}{3} \times \frac{6}{7} = -\frac{12}{21}$

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

$-\frac{12}{21} = -\frac{4}{7}$

Finally, multiply the result by (\frac{1}{10}:

$-\frac{4}{7} \times \frac{1}{10} = -\frac{4}{70} = -\frac{2}{35}$

2. $-\frac{6}{7} \times \left(-\frac{3}{5}\right) \times \frac{6}{5}$:

First, multiply the fractions from left to right:

$-\frac{6}{7} \times \left(-\frac{3}{5}\right) = \frac{18}{35}$

Now, multiply the result by (\frac{6}{5}:

$\frac{18}{35} \times \frac{6}{5} = \frac{108}{175}$

So, the two expressions are equal to:

1. $-\frac{2}{3} \times \frac{6}{7} \times \frac{1/10} = -\frac{2}{35}$
2. $-\frac{6}{7} \times \left(-\frac{3}{5}\right) \times \frac{6}{5} = \frac{108}{175}$
