Question

The closure property does not holds good for integers over 

(1) addition

(2) subtraction 

(3) multiplication 

(4) division

Answer 1

Correct option is (4) division

When we divide an integer by another integer, the quotient may not always be an integer.

For example when we divide 1 by 2 , the quotient is a non-integer.

Also, when the divisor is 0, the quotient is undefined.

Hence, Closure Property does not hold good in integers for division.
