They make up a set of numbers which can be expressed as ratios of two integers, in the form p/q where q is non-zero.

Can numbers be rational and irrational?

It can't be both at the same time. Irrational means "not rational".


How many units are there in rational numbers?

Rational numbers are all whole numbers over 0. It basically means that if you want to say how much cats you have, you use rational numbers. You don't have -8 cats, you don't have 0 cats and hopefully you don't have 3.5 cats. You have 4 cats. There are infinite rational numbers.


Are most numbers rational or irrational?

The set of irrational numbers is larger than the set of rational numbers, as proved by Cantor: The set of rational numbers is "countable", meaning there is a one-to-one correspondence between the natural numbers and the rational numbers. You can put them in a sequence, in such a way that every rational number will eventually appear in the sequence. The set of irrational numbers is uncountable, this means that no such sequence is possible. All rational and irrationals (ie real numbers) are a subset of complex numbers. Complex numbers, in turn, are part of a larger group, and so on.


What is the relationship of rational numbers and real number?

The set of rational numbers is a subset of the set of real numbers. That means that every rational number is a real number, but not every real number is rational. The square root of 2 is an example of a real number that isn't rational; that is, it can't be expressed as the quotient of two integers.


Fraction is a rational numbers but not every rational number is a fraction?

Every rational number can be expressed as a fraction. It's what rational means- a number that can be expressed as a ratio (fraction) of integers.

What are the rational numbers between 1 and 10?

Rational numbers are infinitely dense and that means that there are infiitely many rational numbers between any two numbers.


Are irrational numbers rational numbers?

No. Real numbers are divided into two DISJOINT (non-overlapping) sets: rational numbers and irrational numbers. A rational number cannot be irrational, and an irrational number cannot be rational.


The rational numbers are a subset of the irrational numbers?

No, they are complementary sets. No rational number is irrational and no irrational number is rational.Irrational means not rational.


Is all rational numbers a ratio of two integers?

Yes. When you're talking about numbers, that's what 'rational' means.

Can rational numbers be irrational numbers?

No, they are two separate groups of numbers. A number is either rational or irrational, never both.


What does a word problem using rational number and its solution mean?

It means that either the numbers involved in the word problem are all rational or that any irrational numbers are being approximated by rational numbers.


Is the set of all rational numbers continuous?

Continuity is a characteristic of functions not of sets.The set of rational number is infinitely dense. This means that between any two rational numbers, no matter how close together, there are infinitely many rational numbers. And then, between any two of them these is an infinte number of rational numbers, and so on.But, in case that gives you any wrong ideas, between any two rational numbers there is an even higher order of infinity of irrational numbers. In that respect the number of gaps in the set of rational numbers (where the irrational numbers would be) is greater than the cardinality of rational numbers.Continuity is a characteristic of functions not of sets.The set of rational number is infinitely dense.

non integer rational numbers means the numbers in p/q form and this value is not a perfect integer. ex: 22/7
