Is -5 a rational or irrational?

A rational number is a real number that can be expressed
in the form of fraction p/q, where both p and q are any integers. These integers can be
either positive or negative. However, q cannot be equal to
zero.


Since -5 can be expressed as the fraction  -5/1, it
is a rational number.


Opposite of rational number is
irrational number that cannot be expressed in the form p/q. This means that irrational
numbers can not be represented with absolute accuracy as decimal numbers with limited
digits. Some example of irrational numbers are Pi, square root of 2, cube root of 3, and
cube root of 11. Please note that irrational numbers cannot be expressed correctly as a
fraction
