Question

Whats the numerator for the following rational expression 5/q+9/q=?/q

Answer 1

Answer:  The correct answer is:  " 14 " .

___________________________________________

Step-by-step explanation:

___________________________________________

Note:

$(\frac{a}{c})$  +  $(\frac{b}{c})$  

  =    $\frac{(a+b)}{c}$ ;  

  only if:  $(c\neq0)$ ;  

   →   {since one cannot "divide by 0" .}.

_________________________________________

We are given:

$(\frac{5}{q})$  +  $(\frac{9}{q})$  

         =     $(\frac{?}{q})$  ;    Solve for:  " ? " ;

___________________________________________

Since the "denominators" are the same ; we can solve using the aforementioned "formula";

 →  given that:  " $(q\neq0)$ "  ;  

         →  {since one cannot "divide by 0" .}.

___________________________________________

→  So;  given:

 $(\frac{5}{q})$   +   $(\frac{9}{q})$                                          

                     =   $(\frac{?}{q})$ ;

→ We can simplify the "left-hand side" of the equation               accordingly:

    →  " $(\frac{5}{q})$  +  $(\frac{9}{q})$  "

                    =   $(\frac{(5+9)}{q})$  

                    =   $(\frac{14}{q})$ ;

___________________________________________

   →  " $(\frac{14}{q})$  =  $(\frac{?}{q})$ " ;  

   →  Solve for  " ? " ;

   →  " ? " =  14 .

___________________________________________

The answer is:  " 14 " .

Answer 2

The denominators are equal, so just add the numerators.

5 + 9 = 14

5/q + 9/q = 14/q
