г) \(8\frac{23}{34} \cdot \frac{17}{59} = \frac{8 \cdot 34 + 23}{34} \cdot \frac{17}{59} = \frac{272 + 23}{34} \cdot \frac{17}{59} = \frac{295}{34} \cdot \frac{17}{59} = \frac{295 \cdot 17}{34 \cdot 59} = \frac{5 \cdot 59 \cdot 17}{2 \cdot 17 \cdot 59} = \frac{5}{2} = 2\frac{1}{2}\)
Ответ: \(2\frac{1}{2}\)
