Answer:
11/14
Explanation:
For lunch, Joey ate one-half of the meatballs.
For dinner, Joey ate 2/7 of the meatballs.
The fraction of the meatball that he ate in total will be the total of both fractions.
[tex]\begin{gathered} =\frac{1}{2}+\frac{2}{7} \\ =\frac{7+4}{14} \\ =\frac{11}{14} \end{gathered}[/tex]Joey ate 11/14 of the meatballs in total.
