Answer:The product of two rational numbers is a rational numberStep-by-step explanation:I'll quickly recap the proof: a rational number is, by definition, the ratio between two integers. So, there exists four integers m,n,p,q such that[tex]a=\dfrac{m}{n},\quad b=\dfrac{p}{q}[/tex]If we multiply the fractions, we have[tex]ab = \dfrac{mp}{nq}[/tex]Now, mp and nq are multiplication of integers, and thus they are integers themselves. So, ab is also a ratio between integer, and thus rational.

Answer: the product of two rational numbers is a rational number!Step-by-step explanation:
