The letter R was used for real numbers. So Q, for quotients was used for rational numbers.
Probably, because Q denotes the set of rational numbers, which can formaly understood to be quotients of integers.
The set of irrational numbers is NOT denoted by Q.Q denotes the set of rational numbers. The set of irrational numbers is not denoted by any particular letter but by R - Q where R is the set of real numbers.
There is no special symbol.The set of rational numbers is denoted by Q and the set of real numbers by R so one option is R - Q.
It could be the set denoted by Q- (the non-positive rationals) or Q+ (the non-negative rationals).
Irrational numbers may be denoted by Q' since they are the complement of Q in R, the set of Real numbers.
In number systems Rational number is not represented just by q . they are represented in the form of p and q . P/q is rational number where q is not equal to zero.
Rational numbers are numbers which can be written in the form p/q where p and q are integers and q > 0. Rationals is often used as an abbreviation to refer to the set of all rational numbers.
Rational numbers are numbers which can be expressed as a ratio of two integers, p and q (where q >0), in the form p/q.
The letter Q in blackboard bold is used to represent the set of rational numbers - Q standing for quotient.
The vast majority of rational numbers are not integers. They are numbers which can be written in the form p/q where p and q are integers which are co-prime and q > 1.
They are numbers which are written in the form p/q where p and q are integers.
