Question

PLEASE HELP!!!!!!!!!!!!!!

Answer 1

Answer:

The first answer is correct:

$\{\frac{1}{3},-3.45,\sqrt{9}\}$

Step-by-step explanation:

Since $\frac{1}{3}, -3.45, \sqrt{9}=3$ are all rational numbers, the set that contains those numbers is the set of rational numbers.

In the second set, number $\sqrt{37}$ is irrational number since it can not be written as quotient.

Also in the third and fourth set, numbers $\sqrt{44}$ and $\sqrt{2}$ are irrational numbers.

Therefore, the first answer is correct.
