Ответ:

$-29\frac{52}{63}$

Пошаговое объяснение:

$(-2\frac{1}{8})*(-1\frac{29}{51})=-\frac{2*8+1}{8}*(-\frac{1*51+29}{51})=-\frac{17}{8}*(-\frac{80}{51})=\frac{17*80}{8*51}=\frac{17*8*10}{8*17*3}=\frac{10}{3}$

$(-1\frac{23}{42})*3\frac{1}{3}=-\frac{1*42+23}{42}*\frac{3*3+1}{3}=-\frac{65}{42}*\frac{10}{3}=-\frac{650}{126}=-\frac{325}{63}$

$4\frac{2}{3}*6=\frac{4*3+2}{3}*6=\frac{14}{3}*6=14*2=28$

$\frac{10}{3}+(-\frac{325}{63})-28=\frac{10*63}{3*63}-\frac{325*3}{63*3}-\frac{28*3*63}{3*63}=\frac{630}{189}-\frac{975}{189}-\frac{5292}{189}=\frac{630-975-5292}{189}=\frac{x}{189}=-\frac{5637}{189}=-29\frac{156}{189}=-29\frac{52}{63}$
