\[\boxed{\mathbf{442\ (441).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]
\[Пусть\ x - первое\ число;\ \ \]
\[y - второе\ число.\]
\[1)\ x = \frac{1}{2} \cdot y\ \ \ \ | \cdot 2\]
\[2 \cdot x = \frac{1}{2} \cdot 2 \cdot y\]
\[y = 2x \Longrightarrow второе\ число\ в\ 2\ \]
\[раза\ больше\ первого.\]
\[2)\ x = \frac{3}{2}y\ \ \ \ | \cdot \frac{2}{3}\]
\[\frac{2}{3} \cdot x = \frac{3}{2} \cdot \frac{2}{3} \cdot y\]
\[y = \frac{2}{3}x \Longrightarrow второе\ число\ \]
\[составляет\ \frac{2}{3}\ часть\ от\ первого.\]
