Question

For X = 3 / 4 and Y = - 9/8 insert a rational number between: -
(x-y)^-1and x^-1 - y^-1

Answer 1

Step-by-step explanation:

(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
