Find the sum.
3 and four-ninths plus 5 and one-third equals what number?
A. 8 and five-twelfths
B. 8 and seven-twelfths
C. 8 and five-ninths
D. 8 and seven-ninths
the answer is A.
8 5/12
17 5/9 is what i got am i right
Hmmm. Add this up
3 4/9
5 3/9
---------
8 7/9
how ever did you get 17 5/9 ??? Your first clue should have been that it was not one of the choices ...

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.
To find the sum of 3 and four-ninths (3 4/9) and 5 and one-third (5 1/3), we need to add the whole numbers and fractions separately.
First, let's add the whole numbers: 3 + 5 = 8.
Next, let's add the fractions:
To add 4/9 and 1/3, you need to find a common denominator. The least common multiple of 9 and 3 is 9. To convert 4/9 to a fraction with a denominator of 9, we multiply the numerator and denominator by 1 (9/9): (4/9) * (1/1) = 36/81. To convert 1/3 to a fraction with a denominator of 9, we multiply the numerator and denominator by 3 (3/3): (1/3) * (3/3) = 3/9.
Now, let's add the fractions with the common denominator: 36/81 + 3/9.
Combining the numerators, we get 36 + 3 = 39. The common denominator remains 81/9 = 9.
The sum of the fractions is 39/9.
Finally, combining the whole numbers and the fractions: 8 + 39/9.
To express the sum as a mixed fraction, we divide the numerator (39) by the denominator (9). The quotient is 4 and the remainder is 3. So, the sum 8 + 39/9 can be expressed as 8 and 3/9.
Simplifying the fraction, we can divide both the numerator and denominator by their greatest common divisor (3): 3/9 = 1/3.
Therefore, the sum of 3 and four-ninths plus 5 and one-third is 8 and 1/3.
So the correct answer is not listed among the options provided.
