Answer: There are 4 lemonades that she sold.
Step-by-step explanation:
Since we have given that
Number of gallons of lemonade to sell = 6
Fraction of lemonade she sold = \(\dfrac{2}{3}\)
So, the number of lemonades she sold is given by
\(\dfrac{2}{3}\times 6\\\\=\dfrac{2\times 6}{3}\\\\=\dfrac{12}{3}\\\\=4\)
Hence, there are 4 lemonades that she sold.
