Lucy and Katie sold lemonade. They bought the lemonde in quart-size bottles. They sold 12 cups, using all the lemonade. How many quart- size bottles did they buy?

1 quart = 4 cups

12/4 = ?

To find out how many quart-size bottles Lucy and Katie bought, we need to determine how many quarts are in each cup of lemonade they sold.

Since they sold 12 cups of lemonade, we need to convert that into quarts.

1 quart = 4 cups

To convert cups to quarts, we divide the number of cups by 4.

12 cups ÷ 4 = 3 quarts

So, Lucy and Katie bought 3 quart-size bottles of lemonade.
