rational number

Any number that can be made by dividing one integer by another. [ The word comes from "ratio".
Examples:
1/2 is a rational number (1 divided by 2, or the ratio of 1 to 2)
0.75 is a rational number (3/4)
1 is a rational number (1/1)
2 is a rational number (2/1)
2.12 is a rational number (212/100)
-6.6 is a rational number (-66/10) ]

A whole number is a number that has no decmials. Can be + or -. Whole number are 4,2,23,3535, etc. Numbers such as 4.2,5.5, etc are not.The term whole number is one you’ll find often in mathematics. You may also see the term integer or natural number used in the same manner. Essentially the definition of a whole number is based around what it doesn’t contain. A whole number can’t be a fraction of a number, a percentage, or have a decimal. If you have a number like 21.32, it has a whole number portion (21). But in itself, this number is not a whole number because it contains a fraction (.32).

What is a integer? **Weegy:** Were you wanting a definition of the word integer? The integers (from the Latin integer, literally "untouched", hence "whole": the word entire comes from the same origin, but via French[1]) are natural numbers including 0 (0, 1, 2, 3, [ ...) and their negatives (0, -1, -2, -3, ...). They are numbers that can be written without a fractional or decimal component, and fall within the set {... -2, -1, 0, 1, 2, ...}. For example, 65, 7, and -756 are integers; 1.6 and 1? are not integers. In other terms, integers are the numbers one can count with items such as apples or fingers, and their negatives, as well as 0.
More formally, the integers are the only integral domain whose positive elements are well-ordered, and in which order is preserved by addition.[citation needed] Like the natural numbers, the integers form a countably infinite set. The set of all integers is often denoted by a boldface Z (or blackboard bold \mathbb{Z}, Unicode U+2124 Z), which stands for Zahlen (German for numbers, pronounced ['tsa?l?n]).[2] ] **User:** What is a rational number? **Weegy:** Any number that can be made by dividing one integer by another.

In mathematics, natural numbers are the ordinary counting numbers 1, 2, 3, ... (sometimes zero is also included). Natural numbers have two main purposes: counting and ordering.

Natural Number is the number 1 and any other number obtained by adding 1 to it repeatedly.
