To solve the equation \(\frac{5}{2}x = -\frac{1}{8}\), we need to isolate \(x\).

  1. Start by multiplying both sides of the equation by the reciprocal of \(\frac{5}{2}\), which is \(\frac{2}{5}\):

\[ x = -\frac{1}{8} \cdot \frac{2}{5} \]

  1. Now perform the multiplication on the right side:

\[ x = -\frac{1 \cdot 2}{8 \cdot 5} = -\frac{2}{40} \]

  1. Simplify \(-\frac{2}{40}\):

\[ x = -\frac{1}{20} \]

Thus, the solution to the equation \(\frac{5}{2}x = -\frac{1}{8}\) is:

\[ \boxed{-\frac{1}{20}} \]

The correct response is \(-\frac{1}{20}\) (negative Start Fraction 1 over 20 End Fraction).
