Реши уравнение m-2/11*m=9,9.

Ответ:

\[m - \frac{2}{11}m = 9,9\]

\[m\left( 1 - \frac{2}{11} \right) = 9,9\]

\[m\left( \frac{11 - 2}{11} \right) = 9,9\]

\[\frac{9}{11}m = 9,9\]

\[m = 9,9\ :\frac{9}{11}\]

\[m = \frac{99}{10} \cdot \frac{11}{9} =\]

\[m = \frac{9 \cdot 11 \cdot 11}{10 \cdot 9} = \frac{121}{10}\]

\[m = 12,1.\]

\[Ответ:\ \ m = 12,1.\]
