You can  put this solution on YOUR website! We need common denominators. Then, you can do this 2 ways. Either add the whole numbers and then the fractions or make them all improper fractions and add them. You will get the same answer. The first method is easier.
 
17 2/5 + 14 7/15 + 19 3/10 
17 12/30 + 14 14/30 + 19 9/30 
(17+14+19) + (12/30 + 14/30 + 9/30)   Associative property 
50 + 35/30 
50 + 1 5/30 
51 5/30 
51 1/6
