Question

Find five rational numbers between.
(i)   1/2  and  7/5
(ii)  1/4  and  2/3
(iii)  -5/7 and 3/4

Answer 1

(1).    let x=1÷2 and y=7÷5
formula d=y-x÷n+1
Than  d=7÷5 -1÷2÷5+1
            =14-5÷10÷6
             =9÷10÷6
             =9÷10×6
             =3÷10
than formula=(x+d) ,(x+2d), (x+3d), (x+4d) ,(x+5d)
                 =(1÷2+3÷10) ,(1÷2+3×2÷10) ,(1÷2+3×3÷10) ,(1÷2+3×4÷10) ,(1÷2+3×5÷10)
                 =(5+3÷10), (5+6÷10), (5+9÷10), (5+12÷10), (5+15÷10)
                 =(8÷10) ,(11÷10),(14÷10),(17÷10),(20÷10)ans
