# If a is a rational number and b is a rational number, then the product ab must be?

Rational numbers can be represented as a fraction where the numerator and denominator are integers and the denominator is not equal to zero.

## Answer: If a is a rational number and b is a rational number, then the product ab must be a rational number.

Let's see an example.

**Explanation:**

Let's take two rational numbers,

a = 1/6 and b = 2/3

Product of the two numbers will be:

a × b = (1/6) × (2/3) = 2/18 (rational number)

Thus, we can see that the product of two rational numbers is a rational number.
