Ryan is making some homemade playdough for his students. The playdough recipe calls for 1 cup of salt. If Ryan has 22 cups of salt, how many batches of playdough 23 could he make, assuming he used up all of his salt? Solve using a pictorial representation.
Draw a picture of 2 2/3 cups of salt and mark 1⁄2 cup for each recipe. You should show 4 recipes from 2 cups, and one more recipe from 2/3 with the remainder of 1/6 cup. Since you need 3/6 cup for one recipe but you have only 1/6 cup, this means you can make 1/3 recipe using 1/6 cup. Therefore the answer is 4+1+1/3 = 5 1/3 recipes; then write an equation that represents the story. 2 2⁄3 ÷ 1⁄2 = n or n x 1⁄2 = 2 2⁄3
