Rational Numbers
We will learn how to define rational numbers with examples.
What is rational numbers?
The numbers of the form a/b, or a number which can be expressed in the form a/b, where ‘a’ and ‘b’ are integers and b ≠ 0, are called rational numbers.
In other words, a rational number is any number that can be expressed as the quotient of two integers with the condition that the divisor is not zero.
For examples; each of the numbers 2/3, 5/8, -3/14, -11/-5, 7/-9, 7/-15 and -6/-11 is a rational number.
Numerator and denominator: If a/b is a rational number, then the integer a is known as its numerator and the integer b is called the denominator.
