In mathematics, a rational number is a number that can be expressed as the quotient or fraction $${\displaystyle {\tfrac {p}{q}}}$$ of two integers, a numerator p and a non-zero denominator q. For example, $${\displaystyle {\tfrac {-3}{7}}}$$ is a rational number, as is every integer (e.g. 5 = 5/1). The set of all … Zobacz więcej The term rational in reference to the set $${\displaystyle \mathbb {Q} }$$ refers to the fact that a rational number represents a ratio of two integers. In mathematics, "rational" is often used as a noun abbreviating … Zobacz więcej A finite continued fraction is an expression such as $${\displaystyle a_{0}+{\cfrac {1}{a_{1}+{\cfrac {1}{a_{2}+{\cfrac {1}{\ddots +{\cfrac {1}{a_{n}}}}}}}}},}$$ where an are integers. Every rational number Zobacz więcej The set $${\displaystyle \mathbb {Q} }$$ of all rational numbers, together with the addition and multiplication operations shown above, forms a field. $${\displaystyle \mathbb {Q} }$$ has no field automorphism other than the identity.
