Italian mathematician Giuseppe Peano was the first to designate the set of all types of these numbers Q, from the Italian word for quotient. These numbers are considered a dense subset of real numbers that are countable, and together with addition and multiplication form a field that includes integers. These numbers include any number that can be written as a fraction p over q, in which q is not equal to zero. For 10 points, name these types of numbers that include integers and natural numbers, with examples like 3.1 repeating and 7.86.
