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.
