Решите выражение (д): 30 : \frac{5}{18} : 3\frac{3}{8} - 2\frac{7}{12}

1. \(3\frac{3}{8} = \frac{27}{8}\) 2. \(2\frac{7}{12} = \frac{31}{12}\) 3. \(30 : \frac{5}{18} = 30 \cdot \frac{18}{5} = 6 \cdot 18 = 108\) 4. \(108 : \frac{27}{8} = 108 \cdot \frac{8}{27} = 4 \cdot 8 = 32\) 5. \(32 - \frac{31}{12}\) Общий знаменатель 12. \(32 = \frac{384}{12}\) 6. \(\frac{384}{12} - \frac{31}{12} = \frac{353}{12} = 29\frac{5}{12}\) Ответ: (29\frac{5}{12}\)
