Question

Which property would be used to show that the product of two rational is always rational

Answer 1

You multiply two rational numbers by multiplying numerators and denominators with each other. So, you have

`(a)/(b) * (c)/(d) = (ac)/(bd)`

A rational number is a fraction where both numerator and denominator are integers. Since the product of two integers is an integer, the result fraction is also a rational number, because both
`ac` and
`bd` are integers.
