if i need one third cup of oil for 8 grams of... how much oil do i need for 2 grams

$$\\\frac{1/3}{8}=\frac{x}{2}\\\\ \frac{2/3}{8}=x\\\\ x=\frac{2/3}{8}\\\\$$

$${\frac{\left({\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}{{\mathtt{8}}}} = {\frac{{\mathtt{1}}}{{\mathtt{12}}}} = {\mathtt{0.083\: \!333\: \!333\: \!333\: \!333\: \!3}}$$     

1/12 of a cup
