-$\frac{1}{10}$
Work Step by Step
To divide fractions multiply by the reciprocal of the divisor. Dividing two numbers with opposite signs makes a negative quotient. Reduce fractions by taking out common factors of the numerators and denominators.
-$\frac{5}{16}$$\div$$\frac{25}{8}$=-$\frac{5}{16}$($\frac{8}{25}$)=-$\frac{1}{16}$($\frac{8}{5}$)=-$\frac{1}{2}$($\frac{1}{5}$)=-$\frac{1\times1}{2\times5}$=-$\frac{1}{10}$
