Question

Which of the following are rational numbers {7,-5,2/3,5.79,,√13,√-4}

Answer 1

Answer:

7, -5, 2/3, 5.79

Step-by-step explanation:

rational numbers are numbers you can put in fraction form. $\sqrt{13}$ is not a perfect square, therefore you cannot put it in fraction form. $\sqrt{-4}$ is an imaginary number. Rational numbers are in the Real Numbers category, so it is not a rational number.
