\[\boxed{\mathbf{569\ (569).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 12x = 7\]

\[x = 7\ :12\]

\[x = 0,58(3)\]

\[x \approx 0,58.\]

\[2)\ 5\ :x = 8\]

\[x = 5\ :8\]

\[x = 0,625\]

\[x \approx 0,63.\]

\[3)\ 7x = 16\]

\[x = 16\ :7\]

\[x = 2,2857\ldots\]

\[x \approx 2,29.\]

\[4)\ \frac{3}{8}x = 1\frac{9}{16}\]

\[x = \frac{25}{16}\ :\frac{3}{8}\]

\[x = 4,1(6)\]

\[x \approx 4,17.\]
