Question

that
If a =-2/3, b= 25/7 and c=2-1/6 then show that a-(b-c)is not equal to (a-b)-c.​

Answer 1

Step-by-step explanation:

a=2/3

b=25/7

c=2-1/6=11/6

Now , A. T. Q.

a-(b-c)=(a-b)-c

2/3-(25/7-11/6) =(2/3-25/7)-11/6

2/3-73/42=-61/21-11-6

-45/42=-199/42

Hence A. T. Q.,

a-(b-c)is not equal to(a-b)-c,

-45/42is not equal to -199/42
