Answer 1

Answer:

divide the spume of and by

Answer 2

Answer:

25

Step-by-step explanation:

here the sum of -6/7 and -13/14 is divided by their difference

=  $\frac{-6}{7}+\frac{-13}{14} \\ \frac{-6}{7} -\frac{(-13)}{14}$    

' + ' and ' - ' will make ' - ' and ' - ' and ' - ' will make ' + '

= $\frac{-6}{7}- \frac{13}{14}\\ \frac{-6}{7} +\frac{13}{14}$      

By cross multiplying we get,

= $\frac{-84-91}{98} \\ \frac{-84+91}{98}$  

 Canceling 98 from numerator and denominator we get,

       

= $\frac{-84-91}{-84+91}$            

= $\frac{175}{7}$

= 25
