Question

classify the numbers as rational or irrational. $pi$, $2$, $pi + 2$

Explanation:

A rational number can be written as a fraction $\frac{p}{q}$ where $p$ and $q$ are integers, $q
eq0$. An irrational number cannot be expressed this way.

1. 2 is an integer, so it can be written as $\frac{2}{1}$, making it rational.
2. $\pi$ is a non-repeating, non-terminating decimal, so it is irrational.
3. The sum of an irrational number ($\pi$) and a rational number (2) is irrational.

Answer:

rational: 2
irrational: $\pi$, $\pi + 2$
