Answer
$\pm1,\pm3,\pm\frac{1}{2},\pm\frac{3}{2},\pm\frac{1}{3},\pm\frac{1}{4},\pm\frac{3}{4},\pm\frac{1}{6},\pm\frac{1}{12}$
Work Step by Step
Step 1. $p=\pm1,\pm3$, $q=\pm1,\pm2,\pm3,\pm4,\pm6,\pm12$
Step 2. $\frac{p}{q}=\pm1,\pm3,\pm\frac{1}{2},\pm\frac{3}{2},\pm\frac{1}{3},\pm\frac{1}{4},\pm\frac{3}{4},\pm\frac{1}{6},\pm\frac{1}{12}$
