In order to find the total Jessie sold in these three days, let's add these amounts:
[tex]\begin{gathered} 10\frac{2}{3}+3\frac{1}{3}+2\frac{2}{3} \\ =10+\frac{2}{3}+3+\frac{1}{3}+2+\frac{2}{3} \\ =15+\frac{5}{3} \\ =15+1+\frac{2}{3} \\ =16+\frac{2}{3} \\ =16\frac{2}{3} \end{gathered}[/tex]So Jessie sold 16 2/3 gallons of lemonade in there three days.
