Question 6 of 10

The product of two rational numbers:
A is a rational number.
B. cannot be determined without more information.
O c. is an irrational number.
D. is undefined.

Answer 1

A. is a rational number.

Explanation:

You want to know whether a product of rational numbers is rational.

Product

You know that the product of fractions is ...

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

where a, b, c, d are integers.

A rational number can always be expressed as the ratio of two integers. The product of any two integers is an integer, so the product of any two rational numbers is rational.
