Question

Is 2.89 rational or irrational

Answer 1

Rational

Explanation:

Rational numbers:

Rational numbers are such numbers that can be expressed in the form p/q, where the value of q must not be equivalent to 0.

Irrational numbers:

These numbers cannot be expressed in the form p/q, where the value of q must not be equivalent to 0.

`\implies 2.89 = (289)/(100) \ \ \text{[In} \ \frac{\text{p}}{\text{q}} \ \text{form (\text{q}} \\eq 0)]}`

Thus, 2.89 is a rational number.
