Which number is a ration number when multiplied by 0.25?A. 0.45B. -squard root of 15C. Pie D. 0.53713218

A,DStep-by-step explanation:A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.Product of two rational numbers is always rational.Product of two irrational numbers may or may not be rational.Product of a rational number and a irrational number is rational if the rational number is zero.option A:Both [tex]0.25[/tex] and [tex]0.45[/tex] are rational,So their product is also rational.option B:[tex]0.25[/tex] is irrational but [tex]-\sqrt{15}[/tex] is irrational,So their product is also irrational.option C:[tex]0.25[/tex] is irrational but [tex]\pi[/tex] is irrational,So their product is also irrational.option D:Both [tex]0.25[/tex] and [tex]0.53713218[/tex] are rational,So their product is also rational.
