Q4 of 30 Page 7

Insert three rational numbers between .

We can represent a rational number between two rational numbers a and b as

(a + b)/2


Now, put a = 2/3 and b = 3/5.


Then,


Rational number between 2/3 and 3/5 =


Rational number between 2/3 and 19/30


Rational number between 19/30 and 3/5 =


Hence, three rational numbers between 2/3 and 3/5 are 19/30, 39/60 and 37/60.
