c. 3:1:2
d. 3:2:1
e. 6:3:2

Answer 1

$LCD: 6 \\\frac{1}{2}* \frac{3}{3} = \frac{3}{6} \\\\\frac{1}{3}*\frac{2}{2} = \frac{2}{6} \\To \ Find \ Seth's \ Amount \ , \ Add \ These \ Two \ And \ Subtract \ From \\The \ Whole \\\\\frac{2}{6} + \frac{3}{6} = \frac{5}{6}, \frac{6}{6}-\frac{5}{6} = \frac{1}{6} \\Seth \ Got \ 1/6 \ Of \ The \ Sandwich \\ The \ Ratio \ Is \ 3:2:1 \\\boxed{answer \ choice \ D}$
