Решите пример: (-2 1/8)*(-1 29/51)+(-1 23/42)* 3 1/3 -(-4 2/3)*6= С объяснениями,...

Решите задачу:

$1)-2 \frac{1}{8} *(-1 \frac{29}{51})=- \frac{17}{8} *(- \frac{80}{51} )= \frac{10}{3} =3 \frac{1}{3} \\ 2)-1 \frac{23}{42} *3 \frac{1}{3} =- \frac{65}{42} * \frac{10}{3} = - \frac{325}{63} =-5 \frac{10}{63} \\ 3)-4 \frac{2}{3} *6=- \frac{14}{3} *6=-28 \\ 4)3 \frac{1}{3} +(-5 \frac{10}{63} )=3 \frac{23}{63} -5 \frac{10}{63} =-1 \frac{50}{63} \\ 5)-1 \frac{50}{63} -(-28)=-1 \frac{50}{63} +28=26 \frac{13}{63}$
