Explain six rational numbers between 3 and 4

Let 3 =30/10 and 4 = 40/10

so 6 numbers between them are 31/10 =3.1

32/10=3.2

33/10=3.3

34/10=3.4

35/10=3.5

36/10=3.6 etc

Note that thereare infinite number of rational numbers between any two rational numbers so you may get other rational numbers also
