Elaina, Miguel, and Swati are calculating the product of 6–√

and 2/3
.

Elaina says the answer is irrational because both numbers are irrational.

Miguel says the answer is rational because both numbers are rational.

Swati says the answer is irrational because one number is rational and the other number is irrational.

1 answer

First, let's evaluate each person's statement regarding the product of \( \sqrt{6} \) and \( \frac{2}{3} \).

  1. Elaina's claim: She says the answer is irrational because both numbers are irrational.

    • This claim is incorrect. While \( \sqrt{6} \) is irrational, \( \frac{2}{3} \) is a rational number. The product of a rational number and an irrational number is always irrational, but the reasoning she provides about both numbers being irrational is flawed.
  2. Miguel's claim: He says the answer is rational because both numbers are rational.

    • This claim is incorrect because \( \sqrt{6} \) is not a rational number; it is irrational. Therefore, his conclusion that the product is rational is wrong.
  3. Swati's claim: She says the answer is irrational because one number is rational and the other number is irrational.

    • This claim is correct. The product of \( \sqrt{6} \) (irrational) and \( \frac{2}{3} \) (rational) is indeed irrational.

Therefore, the correct person is Swati.

Enter the number that corresponds to the correct answer: 3
