Question

For any integer a, a ÷ 0 is ______.

• A. a
• B. 0
• C. not defined
• D. 1

Answer 1

The correct option is C

not defined

For any integer a, a ÷ 0 is not defined.
We know that, division is a repeated subtraction.
For example 15÷3 is
15-3 = 12
12-3 = 9
9-3 = 6
6-3 = 3
3-3 = 0
Therefore, 15÷3 = 5.
Similarly 15 ÷ 0 is
15 - 0 = 15
15 - 0 = 15
15 - 0 = 15
15 - 0 = 15 and so on ...
Therefore, division of an integer by 0 is not defined.
