Question

is 2 1/4 an irrational number
Answered by GPT-4o mini
No, \(2 \frac{1}{4}\) (which is equal to \(2.25\)) is not an irrational number. It is a rational number because it can be expressed as a fraction (specifically, \(\frac{9}{4}\)). Rational numbers are defined as numbers that can be expressed as the quotient of two integers, and \(2 \frac{1}{4}\) meets that definition.
