Answer 2

Answer:

In mathematics, a rational number is a number such as -3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.[1] Every integer is a rational number: for example, 5 = 5/1. The set of all rational numbers, often referred to as "the rationals"[citation needed], the field of rationals[citation needed] or the field of rational numbers is usually denoted by a boldface Q (or blackboard bold {\displaystyle \mathbb {Q} }, Unicode /ℚ);[2][3] it was thus denoted in 1895 by Giuseppe Peano after quoziente, Italian for "quotient".



The rational numbers (ℚ) are included in the real numbers (ℝ), while themselves including the integers (ℤ), which in turn include the natural numbers (ℕ)
