Question

name the properties which are not satisfying the set of rational numbers under multiplication​

Answer 1

Subtraction of two rational numbers is not commutative. Therefore, Commutative property is not true for subtraction. The product of two rational numbers is always a rational number. Hence Q is closed under multiplication.

Answer 2

Answer:

Step-by-step explanation:

tep-by-step explanation:

sum of any two rational numbers is always a rational number. This is called ‘Closure property of addition’ of rational numbers. Thus, Q is closed under addition

If a/b and c/d are any two rational numbers, then

(a/b) + (c/d) is also a rational number

Example :

2/9 + 4/9 = 6/9 = 2/3 is a rational number
