\[\boxed{\mathbf{2.482}}\]
Пояснение.
Решение.
\[\textbf{а)}\ \frac{1}{7} \rightarrow 7\]
\[7 > \frac{1}{7}.\]
\[\textbf{б)}\ \frac{2}{9} \rightarrow \frac{9}{2}\]
\[\frac{9}{2} > \frac{2}{9}.\]
\[\textbf{в)}\ \ 1\frac{3}{4} = \frac{7}{4} \rightarrow \frac{4}{7}\]
\[\frac{4}{7} < \frac{7}{4}.\]
\[\textbf{г)}\ 0,3 = \frac{3}{10} \rightarrow \frac{10}{3}\]
\[\frac{10}{3} > \frac{3}{10}.\]
\[\textbf{д)}\ 5,25 = \frac{525}{100} = \frac{21}{4} \rightarrow \frac{4}{21}\]
\[\frac{4}{21} < \frac{21}{4}.\]
