Answer 1

Answer:

-17/27– -11/27

= -17+11/27

= -6/27

= -2/9

Answer 2

Answer:

The other rational number is -2/9

Step-by-step explanation:

Given -

The sum of two rational number is

One of the  rational number is  $\frac{-11}{27}$

To find -

Other rational number  

Solution -

Let, Other rational number is

As per given information

$\frac{-11}{27} +x =\frac{-17}{27}$

$x =\frac{-17}{27}+ \frac{11}{27}$

For subtraction of fraction number both the denominator should be same.

$x =\frac{-17+11}{27}$

$x=\frac{-6}{27}$

Divide by 3 we get

$x= \frac{-2}{9}$

∴ The other rational number is -2/9 .

Answer cross verification -

LHS = $\frac{-11}{27} +x = \frac{-11}{27} + \frac{-6}{27} = \frac{-17}{27}$ = RHS

Ans verified.
