The product of two rational numbers can always be written as _________

A rational number is a number such that it can be expressed as the quotient or fraction p/q of two integers, a numerator p, and a non-zero denominator q. 

Answer: The product of two rational numbers can always be written as a rational number.

We will use the definition of the rational number to explain the product of two rational numbers.

Explanation:

We will take two rational numbers and show that their product is also a rational number.

Suppose we take two rational numbers 1/4 and 2/7

Product of two rational numbers = 1/4 × 2/7 = 1/14, which is a rational number. 

Therefore, a product of two rational numbers can be written as a rational number.
