In English: A rational number
<I'm wondering who is asking all these simpleton questions using very basic grammatical mistakes?>
"In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.[1] Since q may be equal to 1, every integer is a rational number."
