Question

Which of the following is not a number system?

• A. Positional
• B. Octal
• C. Binary
• D. Fractional

Hint:

Remember that a number system refers to the way numbers are represented, like decimal, binary, etc. Fractional refers to a part of a number, not a whole system.

Answer 1

The Correct Option is D

- Positional: A number system where the position of the digits affects their value (e.g., decimal, binary). - Octal: A base-8 number system. - Binary: A base-2 number system. - Fractional: This is not a number system itself; it refers to numbers with fractions (e.g., 1.5, 2.75). Hence, the correct answer is (4).
