Step-by-step explanation:

1)

(-12/5)+2/7=(-84+10)/35= (-74)/35

2/7+(-12/5)=(10-84)/35= (-74)/35

2)(-5/8)+(-9/13)+(-5/8)=2*(-5/8)+(-9/13)

=(-5/4)+(-9/13)

= (-65-36)/52

= -101/52

3)3+(-7/2)+(-7/2)+3=6+2*(-7/2)

=6-7

= -1

4)(2/-7)+(12/-35)=(-70-84)/(35*7). =(-154)/(35*7)=(-22)/35

12/(-35)+2/(-7)=(-84-70)/(35*7)= (-22/35)
