Also a rational number.
In mathematics, a rational number is defined as a number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. For example, 1/2, 3/4, and -5/7 are all rational numbers.
The reciprocal of a rational number is obtained by interchanging the numerator and denominator of the fraction. For example, the reciprocal of 1/2 is 2/1, the reciprocal of 3/4 is 4/3, and the reciprocal of -5/7 is -7/5.
Since the numerator and denominator of a rational number are integers, the reciprocal also has integers as its numerator and denominator. Therefore, the reciprocal of a rational number is always a rational number.
