Answer 1

Answer:

* now we should find a rational number between 4 and 9

so,the rational number between 4 and 9 is a+b/2

here the a=4,b=9

a+b/2 = 4+9/2 = 13/2

13/2= (4+(13/2))/2 =21/4

21/4 = (4+(21/4))/2= 37/8

*continuing this process we get many rational number between 4 and 9

so,here the first rational number is 13/2 and remaining are 21/4 ,37/8
