Final answer:
When you multiply two rational numbers together, the result is also a rational number. Example: 1/2 * 3/4 = 3/8.
Step-by-step explanation:
In mathematics, a rational number is a number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. When you multiply two rational numbers together, the result is also a rational number. This is because when you multiply fractions, you simply multiply the numerators together and the denominators together, resulting in a new fraction.
For example, let's multiply two rational numbers: 1/2 * 3/4 = (1 * 3) / (2 * 4) = 3/8. Both 1/2 and 3/4 are rational numbers, and their product, 3/8, is also a rational number.
