What type of number is the result of multiplying a Rational Number with an Irrational Number?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Sometimes Rational, Sometimes Irrational.
If the rational number is 0, the product is 0, which is rational.
If the rational number is non-zero, the product is irrational (since multiplying a non-zero rational by an irrational gives an irrational).
So it depends on whether the rational number is zero or not.
