Question

Which of the following is true?

Answer 1

C

Explanation:

Consider all options:

A.
`√(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 (1)/(3)` that is
`(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
`-√(16)=-4` and is integer, therefore, is rational number. So, this option is false.
