Explanation:
Hello!
A rational number is any number that can be represented as a fraction with two integers. It includes whole numbers, natural numbers, integers, decimals, and fractions (with only integers).
A decimal is only rational if the decimal places either ends or the numbers repeat. If the decimal places keep going on randomly without a pattern, it is irrational.
We can simplify
to 2, and it can be represented as a fraction of 2/1, so it is rational.
Taking the square root of a non-perfect square is always irrational. But 4 is a perfect square of 2, hence, it is rational.
