To solve the expression \((-2) \times \left(\frac{1}{5}\right) \div \left(\frac{2}{3}\right) \times \left(-\frac{5}{6}\right) \div \left(\frac{3}{4}\right)\), we will follow the order of operations and simplify step by step.

  1. Convert the division by a fraction into multiplication by its reciprocal:

\[ = (-2) \times \left(\frac{1}{5}\right) \times \left(\frac{3}{2}\right) \times \left(-\frac{5}{6}\right) \times \left(\frac{4}{3}\right) \]

  1. Now, we can multiply all these factors together:

\[ = (-2) \times \left(\frac{1}{5}\right) \times \left(\frac{3}{2}\right) \times \left(-\frac{5}{6}\right) \times \left(\frac{4}{3}\right) \]

  1. Combine the numerical coefficients and fractions:

\[ = \frac{(-2) \times 1 \times 3 \times (-5) \times 4}{5 \times 2 \times 6 \times 3} \]

  1. Calculate the numerator:

\[ = (-2) \times (-5) \times 4 \times 3 = 2 \times 5 \times 4 \times 3 = 120 \]

  1. Calculate the denominator:

\[ = 5 \times 2 \times 6 \times 3 = 180 \]

  1. So, we have:

\[ = \frac{120}{180} \]

  1. Simplify the fraction:

\[ = \frac{2}{3} \]

Thus, the final answer is \(\frac{2}{3}\).
