Is 4 12 rational or irrational?

Answer 1

The number (4 \frac{1}{2}) (or 4.5) is a rational number because it can be expressed as the fraction (\frac{9}{2}). Rational numbers are defined as numbers that can be written as the quotient of two integers, and since both 9 and 2 are integers, (4 \frac{1}{2}) is rational.
