Getting the product of two rationals is like multiplying two
fractions, which will have another fraction of this alike form as the result because
integers are sealed under multiplication. All rational number can be signified
as q/r, with q and r are both integers. Another explanation is the product of
two rational numbers is q/r * s/t, with q, r, s, and t are integers.
Nonetheless, this is just (qs)/(rt), and qs and rt are both results of integers
and hence integers themselves. The product of two rational numbers can be
characterized as the quotient of two integers and is itself rational.
Therefore, multiplying two rational numbers yields another rational number.
