 -  frac{40}{63} + ( -  frac{35}{72} ) =  -  frac{40}{63} -  frac{35}{72} =  -  frac{565}{504} =  - 1 frac{61}{504}

 -  frac{19}{60} + ( -  frac{11}{24} ) =  -  frac{19}{60} -  frac{11}{24} =  frac{31}{40}

 -  frac{22}{36} + ( -  frac{31}{48} ) =  -  frac{22}{36} -  frac{31}{48} =  frac{181}{144} =  - 1 frac{37}{144}

Ответ: -40/63+(-35/72) = -40/63-35/72=-565/504

-19/60+(-11/24)=-19/60-11/24=-31/40

-22/36+(-31/48)=-22/36-31/48=-181/144
