Which term describes any number that can be expressed as a fraction?

• A. End Behavior
• B. Complementary Angles
• C. Rational
• D. Transversal

Answer: (C)

Numbers that can be written as a ratio of integers are called rational numbers. This includes integers themselves, since any integer n can be written as n/1, and decimals that terminate or repeat, like 0.5 (1/2) or 0.333... (1/3). In contrast, numbers like sqrt(2) or pi cannot be expressed as a fraction, so they are irrational. The term that describes any number expressible as a fraction is rational. The other terms describe unrelated ideas: end behavior is about how a function behaves as x grows large, complementary angles are two angles that sum to 90 degrees, and a transversal is a line that cuts across two or more lines.
