Question

If P and Q are any two rational numbers then the rational number between P and Q is
a)1/2(p+q)
b)1/2(p-q)
c)1/2(pxq)
d)1/2(p/q

Answer 1

The rational number between P and Q is $\frac{1}{2}(P+Q)$. (option a)

• The rational number between two rational numbers is computed by adding them and then dividing by 2.
• This technique is also used to find the average.
• In this way, many more numbers between any two numbers can be computed.
• Thus, $\frac{1}{2}(P+Q)$ is the rational number between P and Q.
