Answer 2

Given :

Two rational numbers = 1/3 and 2/3

To find :

• A rational number b/w those two numbers.
• For this we need to find the mean of the numbers.

Mean :

If a and b are two rational numbers then rational number between them is (a+b)/2

$\implies$

a = 1/3 , b = 2/3

$\implies \: \dfrac{ \dfrac{1}{3} + \dfrac{2}{3} }{2}$

$\implies \: \dfrac{ \dfrac{3}{3} }{2}$

$\implies \: \dfrac{1}{2}$

Therefore, The rational number b/w them is 1/2
