Answer 1

a rational number includes all the number starting from the positive number, negetive number, whole number and natural numbers

in commutativity you have to you have to change positions of the number ( where there is 2 numbers)

in associativity you have to change the brackets

in distributivity you have to take one common number and do the operation with the both other numbers
