Find four rational numbers between 3/7 and 5/7. Please explain in detail

Dear student,
3/7= (3×10)/(7×10)  [ multiply 10 in numerator and denominator]
      =30/70
5/7= (5×10)/(7×10)   [ multiply 10 in numerator and denominator]
      = 50/70
So, the rational no. between 3/7 and 5/7 is equal to rational no. between 30/70 and 50/70
​​​​​​therefore, required nos.   34/70 , 36/70,   37/70,   39/70 and etc.
Regards
