Question 3: Find five rational numbers between 3/5 and 4/5.
Answer: First method to find rational number between two numbers:
Since we have to find 5 rational numbers between 3/5 and 4/5, so we will mutiply the numerator and denominator of the given numbers by 5+1, i.e. equal to 6.
We get,

=

and

=

=

Now, we have to find 5 rational numbers between 18/30 and 24/30, which will come as
