The set of fractions, such that both the numerator and the denominator are integers. Note that the integers themselves are included; you can write the integer 5, for example, as 5/1.

What is an easy way to define rational?
The answer is rational when you divide one whole number by another one.
Are rational numbers decimals?
A decimal is a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. Any number can have a decimal representation. Rational numbers have decimal representations that are either terminating or recurring whereas non-recurring decimals represent irrational 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 sum if you multiply two rational numbers?
Either way, you'll end up with a rational number, but you won't get a sum if you multiply.
How are rational numbers and whole numbers used in everyday life?
Counting your money would be one way.

What is the easiest way to define osmosis?
The movement of water across a semipermeable membrane.
How do you use negative rational numbers?
Negative rational numbers are used in the same way that negative whole numbers are used: they are simply the additive inverses of their positive counterparts.

Is the number 56 a rational number whole number natural number or irrational number?
56 is a rational whole natural number. Or to put it another way: 56 is a Natural number, but as all natural numbers are also whole numbers 56 is also a whole number, but as all whole numbers are also rational numbers 56 is also a rational number. Natural numbers are a [proper] subset of whole numbers; Whole numbers are a [proper] subset of rational numbers. The set of rational numbers along with the set of irrational numbers make up the set of real numbers

What are the factors of 4 over 15?
There is no meaningful way to talk about factors of rational numbers. A rational can be divided by any other non-zero rational to give a rational and, in that sense, every rational is a factor.
How can you multiply the two 10digit numbers?
the easiest way is to use a calculator.
Why are rational irrational and real numbers not represented in tabular form?
Rational numbers are sometimes represented in tabular form, e.g. for proofs relating to different infinities. Irrational and real numbers are not because there is no way to do it.
How do you define whether a given number is rational or irrational?
A rational number can be expressed as a simple fraction, an irrational number cannot. More formally: A rational number is any real number that can be expressed as a ratio of two integers (positive or negative whole numbers). (The denominator in the ratio cannot be zero.) An irrational number cannot be expressed in that way. The terms "rational" and "irrational" refer to the idea of "ratio".
