3)rational numbers are

Answer 1

Answer:

rational numbers are

commutative for addition

Answer 2

Answer:

answer is rational numbers are commutative for subtraction.

Step-by-step explanation:

let take two rational numbers as 1/2 and -3/5

according to commutative property

(1/2)-(-3/5)=(-3/5)-(1/2)

LHS RHS

(1/2)-(-3/5) (-3/5) -(1/2)

= (1/2)+3/5 = (-6-5) /10

= (5+6)/10 = (-11) /10

= 11/10

since 11/10≠(-11/10)

so this is false
