Answer: Choice D
============================================================
Explanation:
The number 3 is rational since 3 = 3/1. We can write it as a fraction of two integers.
Set of integers = {..., -3, -2, -1, 0, 1, 2, 3, ...} which shows 3 is an integer itself
set of whole numbers = {0, 1, 2, 3, ...} the value 3 is in this set too.
set of natural numbers = {1, 2, 3, ...} same story
In short, the number 3 is rational, an integer, a whole number, and a natural number. This fits with what <u>choice D</u> is saying.
