To solve this problem, we need to find a common denominator for the two fractions. The least common multiple of 9 and 3 is 9, so we will convert 4/9 to have a denominator of 9, and we will convert 1/3 to have a denominator of 9 as well:
3 and 4/9 = 3 + (4/9) = 3 + (4/9) x (3/3) = 3 + 12/27
5 and 1/3 = 5 + (1/3) = 5 + (1/3) x (9/9) = 5 + 9/27
Now we can add the two fractions:
3 + 12/27 + 5 + 9/27 = 8 + 21/27
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 3:
8 + 21/27 = 8 + (21/3)/(27/3) = 8 + 7/9
Therefore, the sum of 3 and four-ninths plus 5 and one-third is 8 and seven-ninths, which is option D.
3 and 4/9 = 3 + (4/9) = 3 + (4/9) x (3/3) = 3 + 12/27
5 and 1/3 = 5 + (1/3) = 5 + (1/3) x (9/9) = 5 + 9/27
Now we can add the two fractions:
3 + 12/27 + 5 + 9/27 = 8 + 21/27
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 3:
8 + 21/27 = 8 + (21/3)/(27/3) = 8 + 7/9
Therefore, the sum of 3 and four-ninths plus 5 and one-third is 8 and seven-ninths, which is option D.
