Г) (8 − 1/2 − 3/8) · 2/5 · 5 · (4 − 1/3 − 2/9)

Решение:

\( (8 - \frac{1}{2} - \frac{3}{8}) \cdot \frac{2}{5} \cdot 5 \cdot (4 - \frac{1}{3} - \frac{2}{9}) \)

1. \( 8 - \frac{1}{2} - \frac{3}{8} = \frac{64}{8} - \frac{4}{8} - \frac{3}{8} = \frac{57}{8} \)
2. \( \frac{2}{5} \cdot 5 = 2 \)
3. \( 4 - \frac{1}{3} - \frac{2}{9} = \frac{36}{9} - \frac{3}{9} - \frac{2}{9} = \frac{31}{9} \)
4. \( \frac{57}{8} \cdot 2 \cdot \frac{31}{9} = \frac{57 \cdot 2 \cdot 31}{8 \cdot 9} = \frac{57 \cdot 31}{4 \cdot 9} = \frac{1767}{36} \)

Ответ: \( \frac{1767}{36} \)
