Question

Set of integers is not closed under ……..

• A. Addition
• B. Subtraction
• C. Multiplication
• D. Division

Answer 1

The correct option is D Division

Integers are closed under addition, subtraction, and multiplication operations. But the division of two integers need not be an integer.

Example:-

$\frac{1}{2}=0.5$

Here, $1$ and $2$ are integers but $0.5$ is not.
