Question

2. In each of the following show that a - (b-c) is not equal to (a - b) -c. a= 5/3 , b= 11/2 , c= -9/4​

Answer 1

Step-by-step explanation:

a-(b-c)

5/3-(11/2+9/4)

5/3-31/4

20-93/12

-73/12-----1

(a-b)-c

(5/3-11/2)+9/4

20-66+27/12

47-66/12

-19/12--------2

from 1 and 2 these are not equal

hence proved
