Question

verify the commutative property of rational number 5/7+(12/5)=-12/5+5/7 pl solve this problem ​

Answer 1

Answer:

Step-by-step explanation:

Let LHS be 5/7 + ( 12/5 ).

And, let RHS be 12/5 + 5/7

Solving LHS:

= 5/7 + 12/5

= (5×5)/35 + (12×7)/35                                                            [equivalent fractions]

= 25/35 + 84/35

= 109/35

Solving RHS:

= 12/5 + 5/7

= (12×7)/35 + (5×5)/35                                                            [equivalent fractions]

= 84/35 + 25/35

= 109/35

Now, as we can observe;

LHS = RHS

Hence, proved commutative property of addition.
