Which set of numbers is always rational? (1 point)

Question

real numbers
decimals
integers
positive numbers

Answer 1

The set of numbers that is always rational is integers.

Integers include whole numbers and their negatives (like -3, -2, -1, 0, 1, 2, 3, etc.), and all integers can be expressed as a fraction (for example, 1 can be written as 1/1).

While some decimals can be rational (like 0.5, which is 1/2), others can be irrational (like π or the square root of 2). Real numbers include both rational and irrational numbers. Positive numbers can also include irrational numbers.

So, the correct answer is integers.
