Question

Identify the rational number.
5/4
-√2
√3
√5

Answer 1

A rational number is defined as a number that can be expressed as the quotient of two integers (a fraction), where the denominator is not zero. Among the options you provided:

1. \( \frac{5}{4} \) is a rational number, as it can be expressed as the fraction of two integers (5 and 4).
2. \( -\sqrt{2} \), \( \sqrt{3} \), and \( \sqrt{5} \) are all irrational numbers, as they cannot be expressed as the quotient of two integers.

Therefore, the rational number among the options is \( \frac{5}{4} \).
