Answer:

Other rational number is (-3/20).

Step-by-step explanation:

We are given that the sum of two rational number is minus 3 upon 5 if one of the number is minus 9 upon 20.

This means that;

Sum of two rational numbers =  

One of the number =  

And we have to find the other rational number.

Let the other rational number be .

So, according to question;

                 Sum of two rational numbers =    

                 One number + Other number =  

                               

  Taking LCM on left side of equation, we get;

                             

                             

Now, using cross multiplication method;

                           

                           

                             

                             

                                 =  

Therefore, the other rational number is    or 0.15.

=>X=-2+3/5

=>X=-10/5+3/5

=>X=-7/5

THEREFORE,THE OTHER NO. IS -7/5
