Explanation:
Rational numbers are numbers that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers.
the results are always a rational number if we multiply add or subtract any two rational numbers.
rational number remains the same if we divide or multiply both of the numerator and denominator with the same factor.
if we add zero to rational number then we get the same number itself
rational numbers are closed under addition subtraction and multiplication
