Ответ:

$\boxed{\bold{3\frac{1}{36} }}$

Пошаговое объяснение:

$3\frac{1}{6} + (-2\frac{5}{9} ) - (-1\frac{17}{12} )$

$3\frac{1}{6} - 2\frac{5}{9} - (-1\frac{17}{12})$

$3+\frac{1}{6} - 2\frac{5}{9} - (-1\frac{17}{12} )$

$3 + \frac{1}{6} - (2+\frac{5}{9} )-(-1\frac{17}{12} )$

$3 + \frac{1}{6} - (2+\frac{5}{9} )--(1+\frac{17}{12} )$

$3+\frac{1}{6} - \frac{23}{9} + \frac{29}{12}$

$3*\frac{6}{6} + \frac{1}{6} - \frac{23}{9} + \frac{29}{12}$

$\frac{3*6}{6} + \frac{1}{6} - \frac{23}{9} + \frac{29}{12}$

$\frac{3*6+1}{6} - \frac{23}{9} + \frac{29}{12}$

$\frac{19}{6} * \frac{3}{3} - \frac{23}{9} + \frac{29}{12}$

$\frac{19}{6} * \frac{3}{3} - \frac{23}{9} * \frac{2}{2} + \frac{29}{12}$

$\frac{19*3}{18} - \frac{23*2}{18} + \frac{29}{12}$

$\frac{19*3-23*2}{18} + \frac{29}{12}$

$\frac{11}{18} + \frac{29}{12}$

$\frac{11}{18} * \frac{2}{2} + \frac{29}{12}$

$\frac{11}{18} * \frac{2}{2} + \frac{29}{12} * \frac{3}{3}$

$\frac{11*2}{36} + \frac{29*3}{36}$

$\frac{11*2+29*3}{36}$
