Question

What are two the rational numbers between 1/3 and 1/5?

Answer 1

By making the denominators same:-
1/3.10/10=10/30
1/5.6/6=6/30
.:2 rational no.s between 10/30 or 1/3 and 1/5 or 6/30 are 7/30
9/30 or 3/10

Answer 2

1/3*5/5=5/15
1/5*3/3=3/15

arrange these both in order
there comes

3/15<4/15<5/15

here you get only one rational number between them now increase the denominator

5/15*2/2=10/30
3/15*2/2=6/30

arrange them in order
you get

6/30<7/30<8/30<9/30<10/30

you get three rational number between them select any two of them
