2. Вычислите: (\frac{2}{3} - \frac{4}{9}) · \frac{3}{8}.

2. Вычислите: $$\left(\frac{2}{3} - \frac{4}{9}\right) \cdot \frac{3}{8}$$.

$$\left(\frac{2}{3} - \frac{4}{9}\right) \cdot \frac{3}{8} = \left(\frac{2 \cdot 3}{3 \cdot 3} - \frac{4}{9}\right) \cdot \frac{3}{8} = \left(\frac{6}{9} - \frac{4}{9}\right) \cdot \frac{3}{8} = \frac{6-4}{9} \cdot \frac{3}{8} = \frac{2}{9} \cdot \frac{3}{8} = \frac{2 \cdot 3}{9 \cdot 8} = \frac{6}{72} = \frac{1}{12}$$

Ответ: $$\frac{1}{12}$$
