To find the total amount of punch that the recipe will make, we need to add together the amount of fruit concentrate and the amount of water.
2 3 cups of fruit concentrate can be written as 2 + 3/4 cups.
6 4 cups of water can be written as 6 + 4/4 cups, or simply 7 cups.
Adding these quantities together, we get:
2 3/4 cups + 7 cups = 9 3/4 cups
Therefore, the recipe will make 9 3/4 cups of punch.
