(1_1/12+1_5/8)*(-1_11/13)-(1_1/12-1_5/8)*1_7/26=Решите пожалуйста по...

$1) 1 \frac{1}{12}+1 \frac{5}{8}= \frac{13}{12}+ \frac{13}{8}= \frac{26+39}{24}= \frac{65}{24}$

$2) \frac{65}{24}*(-1 \frac{11}{13} )= \frac{65}{24}* (- \frac{24}{13} )= - \frac{65}{13}$ =-5

$3) 1 \frac{1}{12}-1 \frac{5}{8}= \frac{13}{12}- \frac{13}{8}= \frac{26-39}{24}=- \frac{13}{24}$

$4) - \frac{13}{24}* \frac{33}{26}=- \frac{11}{16}$

$5) -5+ \frac{11}{16}= \frac{-80+11}{16}=- \frac{69}{16}=-4 \frac{5}{16}$
