Properties of Rational Numbers

The sum of 2 rational numbers is always a rational number ,this is indicator of which propery

• commutative

• closure

• distributive

• associative

The reciprocal of a negative rational number _____

• is a positive rational number

• is a negative rational number

• can be either a positive or a negative rational number

• does not exist

0 is called:

• Identity element for the multiplication of the rational numbers

• Identity element for the addition of rational numbers

• Identity element for the subtraction of rational numbers

• None of these

Division of rational number is

• Commutative

• Closure

• Associative

• None of these

If a, b and c be are three rational numbers, then a+b=b+a; is called

• Closure Property of addition

• Commutative property of Addition

• Associative property of addition

• None of these

If a + (-a )= 0; then ( -a ) is called

• Additive identity of a

• additive inverse of a

• Multiplicative identity of a

• None of these

Multiplicative inverse of zero is-
