What is the relationship between whole numbers integers natural numbers and rational numbers?
Whole numbers are usually defined as the number 0,1,2,3,4,5,6.... where "...." means it goes on forever. These are the natural numbers with the number 0 added to them. So the natural numbers are 1,2,3,4,5,6...
The integers are all the whole number and all the negatives of the natural numbers.
...-4,-3,-2,-1,0,1,2,3,4...
So every whole number is an integer.
Every natural number is an integer.
Every integer is NOT a whole number. ( look at -2)
Every integer is NOT a natural number. ( look at -3)
The set of integers contains the set of natural numbers and contains the set of whole numbers.
The set of whole numbers contains the set of natural numbers.

Are All rationals numbers are in the set of natural numbers?
1. No.The Natural numbers are the positive integers (sometimes the non-negative integers).Rational numbers are numbers that can be expressed as the quotient of two integers (positive or negative). All Natural numbers are in the set of Rational numbers. 2. No. Natural numbers are usually defined as integers greater than zero. A Rational number is then defined simply as a number that can be expressed as an integer divided by a natural number. (This definition includes all rational numbers, but excludes division by zero.)
What is the greatest number that belongs to the sets of integers and rational numbers but not in natural and whole numbers?
the greatest number that is an integer and rational number but is not a natural or whole number is -1
Why is the sum of any two rational numbers a rational number?
== == The set of natural numbers is {1, 2, 3, ...} The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} All natural numbers are integers. A rational number is an integer 'A' divided by a natural number 'B'; i.e. A / B. Suppose we add two rational numbers: A / B + C / D This is algebraically equal to (AD + BC) / BD Since A and C are integers and B and D are natural numbers, then AD and BC are integers because two integers multiplied yields an integer. If you add these together, you get an integer. So we have an integer (AD + BC) on the top. B and D are natural numbers. Multiply them and you get a natural number. So we have a natural number BD on the bottom. Since (AD + BC) / BD is a rational number, A / B + C / D is a rational number. OLD ANSWER: Since a rational number is, by definition, one that can be written a a ratio of 2 integers, adding 2 rationals is tantamount to adding 2 fractions, which always produces a fraction (ratio of 2 integers) for the answer, so the answer is, by definition, rational. llllaaaaaaaaaaaaaalllllllllaaaaaaaaaalllllllllllaaaaaaaaaaaalaaaaaaaa
Family tree of real numbers?
Start with the set of Natural numbers = N.Combine these with negative natural numbers and you get the set of Integers = Z.Combine these with ratios of two integers, the second of which is positive, and you get the set of Rational numbers = Q.Start afresh with numbers which are not rational, nor the roots of finite polynomial equations. This is the set of transcendental numbers.Combine these with the non-rational roots of finite polynomial equations and you have the set of Irrational Numbers.Combine the rational and irrational numbers and you have the set of Real numbers, R.
What is the difference between a rational number and a natural number?
a rational number is different from a natural number because a rational number can be expressed as a fraction and natural numbers are just countinq numbers =D
