Расположите в порядке возрастания числа 1,2; 1 1/3; 1 2/7; 1,4; 1 1/9.

Ответ:

\[1,2;\ \ 1\frac{1}{3};\ \ 1\frac{2}{7};\ \ 1,4;\ \ 1\frac{1}{9}\]

\[1\frac{2}{10};\ \ 1\frac{1}{3};\ \ 1\frac{2}{7};\ \ 1\frac{4}{10};\ \ 1\frac{1}{9}\]

\[1\frac{1}{5};\ \ 1\frac{1}{3};\ \ 1\frac{2}{7};\ \ 1\frac{2}{5};\ \ 1\frac{1}{9}\]

\[1\frac{63}{315};\ \ 1\frac{105}{315};\ \ 1\frac{90}{315};\ \ 1\ \frac{126}{315};\ \]

\[\ 1\frac{35}{315}\]

\[В\ порядке\ возрастания:\]

\[1\frac{1}{9};\ \ \ 1,2;\ \ 1\frac{2}{7};\ \ 1\frac{1}{3};\ \ 1,4.\]
