Identify the limiting ingredient for making s'mores. Each s'more requires 2 graham crackers, 1 piece of chocolate, and 1 marshmallow.
Calculate how many s'mores can be made with the available graham crackers. Divide the total number of graham crackers (7) by the number needed per s'more (2).
Calculate how many s'mores can be made with the available pieces of chocolate. Divide the total number of pieces of chocolate (6) by the number needed per s'more (1).
Calculate how many s'mores can be made with the available marshmallows. Divide the total number of marshmallows (5) by the number needed per s'more (1).
The limiting ingredient is the one that allows the fewest s'mores to be made. Compare the results from the previous steps to determine the maximum number of s'mores that can be made.
