\[\boxed{\ \mathbf{981\ (981)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 9,2 \cdot y = 3,68\]

\[y = 3,68\ :9,2\]

\[y = 0,4\]

\[Ответ:0,4.\]

\[2)\ 0,03y = 0,0162\]

\[y = 0,0162\ :0,03\]

\[y = 162\ :300\]

\[y = 0,054\]

\[Ответ:0,054.\]

\[3)\ y\ :1,2 = 10,2\]

\[y = 10,2 \cdot 1,2\]

\[y = 12,24\]

\[Ответ:12,24.\]

\[4)\ 3,8a + 4,6a = 13,44\]

\[84a = 13,44\]

\[a = 13,44\ :8,4\]

\[a = 1,6\]

\[Ответ:1,6.\]

\[5)\ b - 0,872b = 32\]

\[0,12b = 32\]

\[b = 32\ :0,128\]

\[b = 250\]

\[Ответ:250.\]

\[6)\ 4,9m - 0,1m = 3,84\]

\[4,8m = 3,84\]

\[m = 3,84\ :4,8\]

\[m = 0,8\]

\(Ответ:0,8.\)

\[\boxed{\mathbf{981}\mathbf{.}\mathbf{\ }}\]

\[1)\ \frac{1^{\backslash 10}}{2} = \frac{10}{20};\ \ \ \ \ \ \frac{3^{\backslash 5}}{4} = \frac{15}{20};\ \ \ \]

\[\text{\ \ \ }\frac{4^{\backslash 4}}{5} = \frac{16}{20};\ \ \ \ \ \frac{9^{\backslash 2}}{10} = \frac{18}{20}\text{\ \ }\]

\[2)\ \frac{3^{\backslash 9}}{4} = \frac{27}{36};\ \ \ \ \ \frac{1^{\backslash 6}}{6} = \frac{6}{36};\ \ \]

\[\ \frac{7^{\backslash 2}}{18} = \frac{14}{36};\ \ \ \ \ \frac{8^{\backslash 4}}{9} = \frac{32}{36}\ \]

\[3)\ \frac{1^{\backslash 32}}{2} = \frac{32}{64};\ \ \ \ \ \frac{2^{\backslash 16}}{4} = \frac{32}{64};\]

\[\text{\ \ \ \ }\frac{3^{\backslash 8}}{8} = \frac{24}{64};\ \ \ \ \frac{5^{\backslash 2}}{32} = \frac{10}{64}\]

\[4)\ \frac{1^{\backslash 20}}{5} = \frac{20}{100};\ \ \ \frac{1^{\backslash 25}}{4} = \frac{25}{100};\ \ \]

\[\ \frac{7^{\backslash 4}}{25} = \frac{28}{100};\ \ \ \ \ \frac{63^{\backslash 2}}{50} = \frac{126}{100}\]
