Dear student
$$\begin{gathered} \mathrm{Total}\mathrm{oil}\mathrm{in}\mathrm{can}=15\mathrm{l} \\ \mathrm{Oil}\mathrm{used}\mathrm{for}\mathrm{the}\mathrm{party}=12.18\mathrm{l} \\ \mathrm{Amount}\mathrm{of}\mathrm{oil}\mathrm{left}\mathrm{in}\mathrm{can}=15-12.18=2.82\mathrm{l} \\ \mathrm{Now}1\mathrm{l}=10\mathrm{dc} \\ \mathrm{So},2.82\mathrm{l}=2.82\times 10\mathrm{dl}=28.2\mathrm{dl} \\ \mathrm{So},28.2\mathrm{dl}\mathrm{of}\mathrm{oil}\mathrm{is}\mathrm{left}\mathrm{in}\mathrm{the}\mathrm{can} \end{gathered}$$
