ПОМОГИТЕ!!!!!!!!!!!
-5/8-(-7/12)
5/9-2
-7 7/24-4 13/16
-3 3/14 -(- 2 5/6)

Answer 1

-5/8-(-7/12)=-5/8+7/12=-15/24+14/24=-1/24
5/9-2=5/9-1 9/9=-1 4/9. 
-7 7/24-4 13/16 = -7 14/48 - 4 39/48= - 11 53/48= - 12 5/48
-3 3/14 -(- 2 5/6)= -3 3/14 + 2 5/6= -3 9/42+ 2 35/42= -( 2 51/42 - 2 35/42)= - 16/42 = 8/21.
