a) 5/17-25/31+12/17+(-6/31)

5/17-25/31+12/17-6/31

=(5/17+12/17)-(25/31+6/31)

= 17/17 - 31/31

= 1 - 1

= 0

b)17/8 : ( 27/8 +11/4)

=17/8 : ( 27/8 + 22/8 )

= 17/8 : 49/8

=17/49

c)1/5.11/16+1/5.5/16+4/5

=1/5.11/16+1/5.5/16+1/5.4

=1/5 . ( 11/16 + 5/16 + 4 )

= 1/5 . 5

= 1

d)5/6:25-2+(-7/3).2/7

=5/6.1/25-2+ -2/3

= 1/30 - 60/30 + (-20/30)

= -59/30 + (-20/30)

= -79/30\(\)\(\)
