Amount of lemonade in each pitcher = Seven quarters =
gallons
We have to determine the amount of lemonade in 5 and 1/2 pictures.
First, we will determine the amount of lemonade in 5 pitchers.
So, Amount of lemonade in 5 pitchers =
=
gallons.
Now, we will calculate the amount of lemonade in half of the pitcher =
=
gallons
Total amount of lemonade in 5 and half a pitcher =

LCM of 4 and 8 is '8'.
=
=
gallons.
Therefore, the total amount of lemonade in 5 and 1/2 pictures =
gallons =
gallons.
