Answer 2

To calculate the product of these fractions, simply multiply the numerators together and multiply the denominators together:

$\left(-\frac{7}{9}\right) \times \left(-\frac{2}{13}\right) \times \left(\frac{3}{7}\right) \times \left(-\frac{13}{20}\right) = \frac{7 \times 2 \times 3 \times 13}{9 \times 13 \times 7 \times 20}$.

Now, let's simplify the numerator and denominator:

Numerator: $7 \times 2 \times 3 \times 13 = 546$, Denominator: $9 \times 13 \times 7 \times 20 = 16380$.

So, the simplified fraction is:

$\frac{546}{16380}$.

You can further simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD), which in this case is 6:

$\frac{546 \div 6}{16380 \div 6} = \frac{91}{2730}$.

If you want to reduce this fraction to its simplest form, you can divide both the numerator and the denominator by their GCD, which is 91:

$\frac{91 \div 91}{2730 \div 91} = \frac{1}{30}$.

So, the result of the expression $(-7/9) \times (-2/13) \times (3/7) \times (-13/20)$ is $\frac{1}{30}$.
