Answer 1

Step-by-step explanation:

9

5

and

−12

5

To prove :

9

5

+

−12

5

=

−12

5

+

−9

5

LHS=

9

5

+

−12

5

LCM of 9 and 12=2×2×2×3×3=36

LHS

5×4

5×4

−

12×3

5×3

=

36

20n−15

=

36

5

RHS=

−12

5

+

9

5

=

−12×3

5×3

+

9×4

5×4

(∴LCMof9and12=36)

=

36

−15+20

=

36

5

∴RHS=LHS

i.e

9

5

+

−12

5

=

−12

5

+

9

5

Hence, the commutative property for the addition of rational numbers is verified.
