The set of integers is a proper subset of the set of rational numbers.
A rational number is one which can be expressed as a ratio of two integers.
They are all numbers
No. There are infinitely many rational numbers between any two integers.
An integer is a whole number: a countng number, zero or a negative counting number. That is, an element of the set {..., -3, -2, -1, 0, 1, 2, 3, ...}. A rational number is one that can be expressed in the form x/y where x and y are integers, and y is not zero.

The term "whole number" is somewhat ambiguous. It MAY refer to integers; or it MAY refer only to non-negative integers ("counting numbers").

First of all counting numbers (positive integers) are rational numbers so without rational numbers there would be no counting. You could not equitably share one item between two or more people without fractions (rational numbers). Everything does not come in whole numbers - there are times when you need half-a-day, or 2.5 teaspoons, etc.
Rational numbers are equivalent to ratios of two integers (the denominator being non-zero). A ratio is a relationship between two set of values. For example, the ratio of the circumference of a circle to its diameter is pi, which is not a rational number.
not necessarily... An integer is a rational number, but so is any real number between consecutive integers.

An irrational number is a number that can't be expressed by a fraction having integers in both its numerator and denominator. A rational number can be.
The counting numbers are {1, 2, 3, ...}. The integers are the counting numbers, their opposites (-1, -2, ...) and zero. So they are {..., -2, -1, 0, 1, 2, ...}.
