Question

What are rational numbers?

Answer 1

Hi thula!

A  rational number is a number that can be expressed as a fraction or ratio (rational).  The numerator and the denominator of the fraction are both integers.

When the fraction is divided out, it becomes a terminating or repeating decimal.  

6   or    6/1       can also be written as   6.0

-2  or    -2/1 can also be written as -2.0

  1/2 can also be written as .5

  -5/4 can also be written as -1.25

  23 can also be written as

  2/3 can also be written as 0.666666666...

21/55 can also be written as 0.38181818...

53/83 can also be written as 0.62855421687...

the decimals will repeat

after 41 digits

in other words u can say that

In mathematics, a rational number is a number which can be expressed as a ratio of two integers. Non-integer rational numbers (commonly called fractions) are usually written as the vulgar fraction {a}/{b}, where b is not zero. a is called the numerator, and b the denominator.

Each rational number can be written in infinitely many forms, such as {3}/{6} = {2}/{4} = {1}/{2}, but it is said to be in simplest form when a and b have no common divisors except 1 (i.e., they are coprime). Every non-zero rational number has exactly one simplest form of this type with a positive denominator. A fraction in this simplest form is said to be an irreducible fraction, or a fraction in reduced form.

Answer 2

a rational number is a number which can be expressed as a ratio (fraction) of two integers (The numerator and the denominator of the fraction are both integers).

Each rational number can be written in infinitely many forms, such as 6 / 12 = 3 / 6 = 1 / 2 .

Answer 3

1. Any integers like a natural number ( 1, 2, 3....), zero, and negative numbers.

2. Any decimals that can be simplified into fractions. All numbers that can be simplified into fraction is a rational number.

Answer 4

Rational Number

In mathematics, a rational number is a number which can be expressed as a ratio of two integers. Non-integer rational numbers (commonly called fractions) are usually written as the vulgar fraction a/b, where b is not zero. a is called the numerator, and b the denominator.
