Definition of rational number:

Any number of the form p/q, where p and q are integers and q is not equal to 0, is a rational number. The letter Q stands for the set of rational numbers. In other terms, a number is a rational number if it can be written as a fraction in which the numerator and denominator are both integers.

Definition of LCM:

The LCM method is used to determine the least multiple of two or more numbers. Least Common Multiple is referred to as LCM. The LCM of two numbers can be divided by both of them. The LCM of 6 and 8 is 24, for instance. 24 can be divided by both 6 and 8 as a result.

Given:

$x = 3/4$

$y = -9/8$

Find:

insert a rational number between  $(x+y)-1 and X-1 + y-1$

Solution:

$(x + y)-1 and X-1 + y-1$

$(\frac{3}{4} +\frac{9}{8} )-1 and (\frac{3}{4} )-1 +(\frac{-9}{8} )-1$

LCM of 8 and 4 is 8

$(\frac{6-9}{8} )-1 and (\frac{4}{3} )-(\frac{8}{9} )$

$\frac{-8}{3} and \frac{12-8}{9}$

$\frac{-8}{3} and \frac{4}{9}$

$\frac{-24}{9} and\frac{4}{9}$

One rational number between $\frac{-24}{9} and\frac{4}{9}$ is  $\frac{1}{9}$.
