Question

how to verify commutativity of addition of rational numbers

Answer 1

Answer:

see the above pic

Step-by-step explanation:

here commutative property

you just have to keep in mind that

in commutative property for addition a+b=b+a

it means that whether you change the place of the number for addition but the solution or the answer will be the same..

now for commutative property for multiplication a×b=b×a

same here only difference is multiplication

means if u change the places but the solution or the answer will be same

and this thing only can be done in commutative property and that also only in addition and multiplication

commutative property never states for subtraction and division

if u will try for subtraction and division the solution or the answer will be wrong

hope now it is clear
