Hi! The answer is 8 ounces of canned tomatoes and 1 cup of cooking macaroni.
This is because you want a quarter (1/4) of the servings so you only need a quarter of the ingredients and to get a quarter of something you just need to divide it by 4 so
Are you being asked to complete the question so that it would make sense? because it would make sense to me to be either a or b if not, then could you please specify?
