What is the greatest number that belongs to the set of integers and rational numbers but not to set of natural numbers and whole numbers?
There is no such number. All of these sets go on forever.
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.)
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.
Are rational numbers always sometimes or never natural numbers?
Sometimes. A rational number is any number that can be written in the form p/q where p and q are integers but q not = 0. So 3 is a natural number and a rational number because it can be written as 3/1. But 1/3 is a rational number only because it will not reduce to a natural (whole) number.
What is the greatest number that belongs to the sets if integers and rational numbers but not to the sets of natural numbers and whole numbers?
the answer is -1
What is the greatest number that belongs to the set of integers and rational numbers but not to set of natural numbers and whole numbers?
There is no such number. All of these sets go on forever.
What kind of numbers belongs to the family of real numbers?
Numbers that include real numbers are natural numbers, whole numbers, integers, rational numbers and irrational numbers.
Are natural numbers whole numbers and integers also rational numbers?
Yes. Every whole number and every whole negative number and zero are all integers.
Is 7 rational or irrational?
7 is a rational number because whole numbers, integers, and natural numbers fit under rational and 7 is a natural number:)Yes.
When are rational numbers not natural?
Most of the time. For example, when they are negative integers.
Are All rationals numbers are in the set of natural numbers?

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.)
How is a rational number defined?
A rational number is a continuous quantity that is a quotient of two integers in which the second integer is a natural number. Rational numbers include the integers as well as non-integers such as fractions and decimals. Rational numbers are the direct result of the arithmetical operation of division.
How are integers and rationals numbers different?
All integers are rational numbers, not all rational numbers are integers. Rational numbers can be expressed as fractions, p/q, where q is not equal to zero. For integers the denominator is 1. 5 is an integer, 2/3 is a fraction, both are rational.
What is the relation between integers natural numbers whole numbers rational and irrational numbers?
Natural numbers = Whole numbers are a subset of integers (not intrgers!) which are a subset of rational numbers. Rational numbers and irrational number, together, comprise real numbers.

Can a number be both natural and irrational?
No. "Natural" numbers are the counting numbers, otherwise known as the positive integers. They are all rational.
