п) \(\frac{13}{43} \cdot 8\frac{7}{26}\).

п) \(\frac{13}{43}\) \(\cdot\) 8\(\frac{7}{26}\) = \(\frac{13}{43}\) \(\cdot \frac{8 \cdot 26 + 7}{26}\) = \(\frac{13}{43}\) \(\cdot \frac{208 + 7}{26}\) = \(\frac{13}{43}\) \(\cdot \frac{215}{26}\) = \(\frac{13 \cdot 215}{43 \cdot 26}\) = \(\frac{13 \cdot 5 \cdot 43}{43 \cdot 2 \cdot 13}\) = \(\frac{5}{2}\) = 2\(\frac{1}{2}\)

Ответ: 2\(\frac{1}{2}\)
