First, add up the whole parts: 3+5+9+14 = 31
Then add up the fractions: 1/9 + 1/3 + 4/9
To do this, you need to convert 1/3 to 3/9 so that they all have the same denominator.
1/9 + 3/9 + 4/9 = 8/9 (When adding fractions with the same denominator, just add the numerators.)
Then put the pieces back together: 31 and 8/9
