Question

Which of the following is true?

Answer 1

Answer:

C

Step-by-step explanation:

Consider all options:

A. $\sqrt{2}$ is irrational number because it cannot be represented as a fraction with integer numerator and natural denominator. This option is false.

B. Number 0 is integer number, therefore, its rational number. This option is false.

C. Repeating decimal $1.\overline{3}$ can be represented as $1 \dfrac{1}{3}$ that is $\dfrac{4}{3}$ and, therefore, this number is rational number. This number is not integer number, because this is a fraction when simplified to lowest terms. So, this option is true.

D. Number $-\sqrt{16}=-4$ and is integer, therefore, is rational number. So, this option is false.
