Let's make them both improper.

 

14*5+11=81, so 81/14 is the improper fraction of 5 11/14

 

Change the denominators to 56.

 

81*4=324, so 324/56 is the first fraction.

 

31*7=217, so 217/56 is the second fraction.

 

324+217= 541

----- -----   ----- 

 56   56      56

 

 

541/56 = 9.66

 

\(9{66\over100}\)

 

Simplify

 

\(9{33\over50}\)

 

So, \(5{11\over14}+{31\over8}=9{33\over50}\)
