Выражение: \(\frac{3}{4} \cdot \frac{1}{15} + 1\frac{1}{15} \cdot 2 - 1\frac{1}{8} \cdot 1\frac{3}{15}\)
1) \(\frac{3}{4} \cdot \frac{1}{15} = \frac{3}{60} = \frac{1}{20}\)
2) \(1\frac{1}{15} \cdot 2 = \frac{16}{15} \cdot 2 = \frac{32}{15}\)
3) \(1\frac{1}{8} \cdot 1\frac{3}{15} = \frac{9}{8} \cdot \frac{18}{15} = \frac{162}{120} = \frac{27}{20}\)
4) \(\frac{1}{20} + \frac{32}{15} - \frac{27}{20}\) = \(\frac{3 + 128 - 81}{60} = \frac{50}{60} = \frac{5}{6}\)
Ответ: \(\frac{5}{6}\)
