Honors Mathematics 3 Practice Exam

Any number that can be expressed as a fraction describes which concept?

Rational End Behavior Complementary Angles Transversal

Correct Answer:

Rational

Explanation:

Rational numbers are exactly the numbers that can be written as a ratio of two integers, with a nonzero denominator. This includes integers (like 5, which is 5/1), fractions, and decimals that terminate or repeat (such as 0.75 = 3/4 or 0.333... = 1/3). In contrast, numbers like π or √2 cannot be written as a fraction of integers, so they’re irrational. The other terms aren’t about how numbers can be expressed as fractions: end behavior describes what a function does as x grows large, complementary angles are two angles that sum to 90 degrees, and a transversal is a line that intersects two or more lines. So the description matches rational numbers.
