A natural number is a positive integer.
A rational number is a number that may be expressed as the ratio of natural numbers such as 1/3.
Not all numbers may be expressed as the ratio of natural numbers, such as the square root of 2 or pi.

That natural numbers are the 'counting' numbers. They arise out of the basic need to count finite sets things. Some people consider zero to be a natural number, others say that the natural numbers start with one.
Rationals are numbers which can be represented as a ratio of integers, with the denominator non-zero.
Integers are the counting numbers and the negatives of the counting numbers, and zero (if you didn't define zero as a counting number.)
