$\dfrac{1}{4}$
Work Step by Step
Factor 32 to obtain:
$=\left(-\dfrac{8}{10}\right)\left(-\dfrac{10}{8(4)}\right)$
Cancel the common factors to obtain:
$\require{cancel}
=\left(-\dfrac{\cancel{8}}{\cancel{10}}\right)\left(-\dfrac{\cancel{10}}{\cancel{8}(4)}\right)
\\=(-1) \cdot \left(-\dfrac{1}{4}\right)
\\=\dfrac{1}{4}$
