Решение:
- \( \frac{y}{0,8} = \frac{23}{4} \)
\( y = 0,8 \cdot \frac{23}{4} \)
\( y = \frac{8}{10} \cdot \frac{23}{4} \)
\( y = \frac{2}{10} \cdot 23 \)
\( y = \frac{1}{5} \cdot 23 \)
\( y = \frac{23}{5} = 4,6 \) - \( x : 2\frac{3}{23} = 3\frac{3}{4} : \frac{1}{4} \)
\( x : \frac{49}{23} = \frac{15}{4} : \frac{1}{4} \)
\( x : \frac{49}{23} = \frac{15}{4} \cdot 4 \)
\( x : \frac{49}{23} = 15 \)
\( x = 15 \cdot \frac{49}{23} \)
\( x = \frac{735}{23} \)
Ответ: 1) \(y = 4,6\); 2) \(x = \frac{735}{23}\).
