Answer:
OK,
Step-by-step explanation:
(3/5+7/3)-11/6
=(9+35/15)-11/6
=44/15-11/6
=264-165/90
=101/90
so, they are not equal

Step-by-step explanation:
Given,
a = 3/5
b = -7/3
c = 11/6
(a - b) - c:
==> (3/5 - (-7/3)) - 11/6
==> (3/5 + 7/3) - 11/6
LCM of 3, 5, 6 is 30.
==> (3*6 + 7*10 - 11*5) / 30
==> (18 + 70 - 55) / 30
==> 33/30
==> 11/10
a - (b - c):
==> 3/5 - (-7/3 - 11/6)
==> 3/5 + 7/3 + 11/6
LCM of 3, 5, 6 is 30.
==> (3*6 + 7*10 + 11*5) / 30
==> (18 + 70 + 55) / 30
==> 143 / 30
==> 11/10 ≠ 143/30
==> [ (a - b) - c ] ≠ [ a - (b - c) ]
Hence Proved.
