Answer:
(51)/(10)

Explanation:

In order to add fractions, we need to make sure that the denominators are the same. Since 2 and 5 are different, we can make them a common denominator of 10.


(5*7)/(5*2) +(2*8)/(2*5) [multilpy first fraction by 5/5 and second by 2/2]


(35)/(10) +(16)/(10) [add numerators]


(35)/(10) +(16)/(10)=(51)/(10)

Therefore, the answer is
(51)/(10).
