R was used for Real numbers. Q, for rational numbers refers to the fact that it must be possible to express them as quotients [of two integers].

What is the symbol of a rational number?
The set of rational numbers is represented by Q.
Why set of rational number is denoted by q?
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.
What is the symbol of irrational 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.
Is the square root of an irrational number rational?
No: Let r be some irrational number; as such it cannot be represented as s/t where s and t are both non-zero integers. Assume the square root of this irrational number r was rational. Then it can be represented in the form of p/q where p and q are both non-zero integers, ie √r = p/q As p is an integer, p² = p×p is also an integer, let y = p² And as q is an integer, q² = q×q is also an integer, let x = q² The number is the square of its square root, thus: (√r)² = (p/q)² = p²/q² = y/x but (√r)² = r, thus r = y/x and is a rational number. But r was chosen to be an irrational number, which is a contradiction (r cannot be both rational and irrational at the same time, so it cannot exist). Thus the square root of an irrational number cannot be rational. However, the square root of a rational number can be irrational, eg for the rational number ½ its square root (√½) is not rational.
How are the rules for adding integers applied to operations with rational numbers?
You need the rules of multiplication as well as of addition. But multiplication of integers can be viewed as repeated addition. Thus, if p/q and r/s are two rational numbers then their sum is(p*s + q*r)/(q*s)
How do you write an irrational number in algebra?
There is no representation for irrational numbers: they are represented as real numbers that are not rational. The set of real numbers is R and set of rational numbers is Q so that the set of irrational numbers is the complement if Q in R.
Why Q is represented for rational numbers?
It stands for the quotient. The letter R stands for the set of Real numbers.
What is the symbol of a rational number?
The set of rational numbers is represented by Q.
Why are rational numbers denoted as Q?
The letter R was used for real numbers. So Q, for quotients was used for rational numbers.
How do you add and subtract rational numbers?
A rational number is a number of the form p/q where p and q are integers and q > 0.If p/q and r/s are two rational numbers thenp/q + r/s = (p*s + q*r) / (q*r)andp/q - r/s = (p*s - q*r) / (q*r)The answers may need simplification.
What represents a whole numbers and fractions?
The set is represented by Q. They form the set of rational numbers and the Q comes from quotient.
What are the rules for multiplying rational numbers?
p/q * r/s = (p*r)/(q*s)
What do you do while multiplying rational numbers?
A rational number is a number which can be expressed in the form p/q where p and q are integers and p>0.If p/q and r/s are two rational numbers then(p/q)*(r/s) = (p*r)/(q*s).You may need to check that this fraction is in its lowest (simplest) form.
What is the symbol used for irrational numbers?
There is no specific symbol. The symbol for real numbers is R and that for rational numbers is Q so you could use R \ Q.
What is the charateristics of rational numbers?
The defining characteristic is that they can be represented in the form of a ratio, p/q, of two integers, where q > 0.
Why set of rational number is denoted by q?
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.
What is the symbol of irrational 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.
