д) \(\frac{57}{37} \cdot \frac{74}{76}\) = \(\frac{57 \cdot 74}{37 \cdot 76}\) = \(\frac{57 \cdot 2 \cdot 37}{37 \cdot 4 \cdot 19}\) = \(\frac{57 \cdot 2}{4 \cdot 19}\) = \(\frac{3 \cdot 19 \cdot 2}{4 \cdot 19}\) = \(\frac{3 \cdot 2}{4}\) = \(\frac{3}{2}\) = 1\(\frac{1}{2}\)

Ответ: 1\(\frac{1}{2}\)
