Question

what are the properties of addition, subtraction, multiplication and division of rational numbers
​

Answer 1

Answer:

Properties of rational numbers:

1. Closure Property :                      

1 + 2 = 3

2 - 1 = 1

1 x 2 = 2

2 ÷ 1 = 2

2.Commutative Property :

1 + 2 = 2 + 1

1 x 2 = 2 x 1

3. Associative Property:

1 + ( 2 + 3) = ( 1 + 2 ) + 3

1 x ( 2 x 3) = ( 1 x 2 ) x 3

4.Distributive Property:

a(b + c) = ab + ac

2(3 + 4) = 2×3 + 2×4
