Question

Encircle the odd one of the following.

Options

• (–100) ÷ 5

• (–81) ÷ 9

• (–75) ÷ 5

• (–32) ÷ 9

Answer 1

(–32) ÷ 9

Explanation:

1. (–100) ÷ 5 = `(-100)/5` = –20
2. (–81) ÷ 9 = `(-81)/9` = –9
3. (–75) ÷ 5 = `(-75)/5` = –15
4. (–32) ÷ 9 = `(-32)/9`

Here, –20, –9, –15 all are integers but `(-32)/9` is not an integer.

∴ (-32) ÷ 9 is different.
