  1. Calculate the portion of each mix below that is chocolate chips, expressing your answer as a percent. Which recipe has the greatest concentration of chocolate chips?

    For Recipe A, find the total number of cups in the recipe.

    Next, write a fraction expressing the portion that is chocolate chips.

    Convert the fraction into a percent.
