2. Вычислите: $$\left(\frac{6}{5}-\frac{3}{4}\right) \cdot \frac{2}{3}$$.

$$\left(\frac{6}{5}-\frac{3}{4}\right) \cdot \frac{2}{3} = \left(\frac{6 \cdot 4}{5 \cdot 4}-\frac{3 \cdot 5}{4 \cdot 5}\right) \cdot \frac{2}{3} = \left(\frac{24}{20}-\frac{15}{20}\right) \cdot \frac{2}{3} = \frac{9}{20} \cdot \frac{2}{3} = \frac{9 \cdot 2}{20 \cdot 3} = \frac{18}{60} = \frac{3}{10} = 0.3$$ Ответ: 0.3
