Question

which of the following describe 5? select all that apply. irrational number integer real number whole number

Explanation:

1. Analyze "irrational number": An irrational number is a number that cannot be expressed as a fraction of two integers. But \( 5=\frac{5}{1} \), so 5 is rational, not irrational. So this option is incorrect.
2. Analyze "integer": Integers include all positive and negative whole numbers and zero. 5 is a positive whole number, so it is an integer. This option is correct.
3. Analyze "real number": Real numbers include all rational and irrational numbers. Since 5 is rational, it is also a real number. This option is correct.
4. Analyze "whole number": Whole numbers are non - negative integers (0, 1, 2, 3, ...). 5 is a non - negative integer, so it is a whole number. This option is correct.

Answer:

The correct options are:
B. integer
C. real number
D. whole number

(Note: Here we assume the options are labeled as A. irrational number, B. integer, C. real number, D. whole number for the purpose of answering. The original incorrect option "irrational number" is excluded.)
