Question

Insert six rational no. Between 3 and 4

Answer 1

3 can be written as 3/1 
4 can be written as 4/1
  multiply both numbers by 7/7
= 3/1 * 7/7 And 4/1 * 7/7
= 21/7 and 28/7
= 22/7 , 23/7 , 24/7, 25/7 ,26/7, 27/7 
So 22/7 , 23/7 , 24/7, 25/7 ,26/7, 27/7  are 6 numbers between 3 and 4

NOTE:- we must always multiply with 1 number greater than asked numbers between 2 numbers

Answer 2

3 = 3×7=21=21/1                                                                  4 = 4×7 = 28=28/1
      1×7=1                     AND                                                       1×7 = 1

We know that 21 is lesser than 22 is lesser than 23 is lesser than than 24 is lesser than 25 is lesser than 26 is lesser than 27 is lesser than 28.

Hence,six rational numbers between 3=21/7  and 4 = 28/7 is

22/7 ,  23/7  , 24/7   ,  25/7  ,  26/7  ,  27/7
