To solve the equation 5/2x = -1/8, you can start by multiplying both sides of the equation by the reciprocal of 5/2, which is 2/5. This will allow you to isolate x.

(5/2x) * (2/5) = (-1/8) * (2/5)

On the left side, the 2 in the numerator and the 2 in the denominator cancel out, leaving you with:

(x) = (-1/8) * (2/5)

Multiply the numerators together and the denominators together:

x = (-1 * 2) / (8 * 5)

Simplify the expression:

x = -2/40

The solution to the equation is x = -1/20 or negative Start Fraction 1 over 20 End Fraction.
1/20 ÷ 5/2 is -1/8
