A rational number and an irrational number are multiplied together. The product is a rational number. What type of rational number must the product be?(1 point)

When you multiply a rational number by an irrational number, the product is typically irrational. The only exception to this is when the rational number is zero, as multiplying zero by any number (rational or irrational) results in zero, which is a rational number.

Therefore, the answer is:

**zero**
