$\bf 12 \: \times \: \bigg( \frac{11}{12} \: - \: \frac{9}{10} \: \bigg) \: \times \: \bigg( 3 \: - \: 1 \frac{1}{3} \bigg) = \\ \\ \\ \bf = 12 \: \times \: \bigg( \underbrace{ \frac{11}{12} \: - \: \frac{9}{10} }_{\sf \green{Numitor \: comun \: \rightarrow \: 120}} \: \bigg) \: \times \: \bigg( \underbrace{ 3 \: - \: \frac{4}{3}}_{\sf \green{Numitor \: comun \: \rightarrow \: 3}} \bigg) = \\ \\ \\ \bf = 12 \: \times \: \bigg( \frac{110 \: - \: 108}{120} \bigg) \: \times \: \bigg( \frac{9 \: - \: 4}{3} \bigg) = \\ \\ \\ \bf = 12 \: \times \: \frac{\not2_{\blue{ \: (1}}}{\not120_{\blue{ \: (60}}} \: \times \: \frac{5}{3} = \\ \\ \\ \bf = \not12_{\blue{\: (1}} \: \times \: \frac{1}{\: \: \not60_{\blue{\: (5}}} \: \times \: \frac{5}{3} = \\ \\ \\ \bf = \frac{1}{\not5} \: \times \: \frac{\not5}{3} = \\ \\ \\ \red{\bf = \boxed{\bf \frac{1}{3}} \: \rightarrow \: \underline{\bf rezultat}}$
