Пошаговое объяснение:
1)5/16+(-5/12)=15/48-20/48=-5/48
-5/48*(-16/25)=1/15
2) - 8/9+7/12=-32/36+21/36=-11/36
-11/36*9/22=-1/8
3) - 8/15-(-16/35)=-56/105+48/105=
-8/105
-8/105*21/44=-2/55
4) 7/8-5/12=21/24-10/24=11/24
11/24*(-8/33)=-1/9
5) 5/8+(-3/4)=5/8-6/8=-1/8
-1/8:5/16=-1/8*16/5=-2/5
6) 9/16+(-7/12)=27/48-28/48=-1/48
-1/48:5/32=-1/48*32/5=-2/15
