A rational number is any number that can be expressed as the quotient or fraction of two integers, a numerator p and a non-zero denominator q.
Examples[edit | edit source]
Notice the number 5 in second example! It is because all numbers are divisible by 1 and at such it is actually but it is more convenient to write it as 5. Note Though all numbers are divisible by 1 some numbers are considered irrational ie they cannot be represented in the form also note that it impossible to have a number with 0 as the denominator (b must not be equal to 0 in ).
