Which statement describes Rational Numbers?

• A. Only integers
• B. Any number that can be expressed as a fraction.
• C. Only decimals
• D. Only square roots

Answer: (B)

Rational numbers are numbers that can be written as a fraction with integers in the numerator and denominator (where the denominator isn’t zero). That means any number like 3, -7, 1/2, or 0.75 fits, because each can be expressed as a ratio of two integers (3 = 3/1, -7 = -7/1, 1/2, 3/4). Decimals that terminate or repeat correspond to fractions, so they’re rational too (0.75 = 3/4, 0.333... = 1/3). Numbers like pi or √2 aren’t rational because they can’t be written as a ratio of integers. So the statement that best describes rational numbers is any number that can be expressed as a fraction.
