Помогите пожалуйста срочно умоляю

Answer 1

2) $-frac{40}{63} - frac{35}{72} =-1 frac{61}{504}$
4) $- frac{19}{60} - frac{11}{24} =- frac{31}{40}$
6) $- frac{23}{36} - frac{31}{48} =-1 frac{41}{144}$

Answer 2

2)
-40/63 + (-35/72) = -40/63 - 35/72 = -320/504 - 245/504 =
= - 565/504 = - 1 61/504,

3)
-19/60 + (-11/24) = -19/60 - 11/24 = -38/120 - 55/120 = -93/120 = - 31/40,

4)
-23/36 + (-31/48) = -23/36 - 31/48 = -92/144 - 93/144 =
= - 185/144 = - 1 41/144
