Второе задание:
\( \frac{5}{14} - 2\frac{1}{4} : (0.6 - 3.28 - 5.468) \)
\( = \frac{5}{14} - \frac{9}{4} : (0.6 - 8.748) \)
\( = \frac{5}{14} - \frac{9}{4} : (-8.148) \)
\( = \frac{5}{14} - (\frac{9}{4} \times \frac{1}{-8.148}) \)
\( = \frac{5}{14} - \frac{9}{-32.592} \)
\( = \frac{5}{14} + \frac{9}{32.592} \)
\( \approx 0.357 + 0.276 \approx 0.633 \)
Ответ: ≈ 0.633
