Answer 1

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