Mrs. McGlashan is making paint for her class. She needs 3/4 cups of warm water for each batch. Part A. Mrs. McGlashan has a 1 cup measure that has no markings can she make 8 batches of paint using only the 1 cup measuring cup? describe two ways you can find the answer. Part B. The paint recipe also calls for 1/4 cup of food coloring. Tyler says Mrs. McGlashan will also need 6cups of food coloring. Do you agree or disagree? Explain.
Part A: You can take a ruler and divide the 1 cup measuring cup into 4 equal parts. Part B: I would have to disagree, because to do it you would have to take 1/4 cup and multiply it by 8 and you should end up with 2 not 6.
