There are \(\frac{1}{3}\) gallons of lemonade.
Two friends share the lemonade.
What fraction of the lemonade does each friend receive?
To solve you do kcf or keep change flip.
You keep \(\frac{1}{3}\) and change division to multiplication.
Then \(\frac{2}{1}\) is changed to \(\frac{1}{2}\)
The answer would be \(\frac{1}{6}\)
Hope That Helps!
