\[x\ :y = \frac{1}{3}:4\]
\[\frac{x}{y} = \frac{1}{12}\]
\[x = \frac{y}{12}.\]
\[2)\ y\ :z = 6\ :5\]
\[\frac{y}{z} = \frac{6}{5}\]
\[z = \frac{5y}{6}\]
\[\frac{y}{12} + y + \frac{5y}{6} = 92\]
\[\frac{y + 12y + 10y}{12} = 92\]
\[23y = 1104\]
\[y = 48.\]
\[4)\ x = \frac{y}{12} = \frac{48}{12} = 4\]
\[z = \frac{5y}{6} = \frac{5 \cdot 48}{6} = 40.\]
\[Ответ:92 = 4 + 48 + 40.\]
