3. For x=
3
and y =
4
insert a rational number between:
8
(i) (x + y)-1 and x-1 + y-1
(ii) (x - y)-1 and x-1-y-1​

Answer 1

Answer:

(x+y)-1 =(3/4-9/8)-1 =([6-9]/8)-1 =(-3/8)-1 =([-3-8]/8) =(- 11/8) x-1+y-1=x+y-2 =3/4-9/8-2 =(6-9-16)/8 =(-19/8) therefore the between rational numbers are -12/8;-13/8;-14/8;-15/8;-16/8;-17/8;-18/8.
