Happy Monday! Our Math Monday blog assignment for today is to explain which method would be better to use in purchasing food for sale at a restaurant, ratio or percentage?
My answer for this is pretty clear, but confusing at the same time. I think that in purchasing food to sell again, you'd need to use both the ratio and percentage to find out a price. I'd probably use percentage more, though. When you find out how much of the original price you are going to sell any retail item for, most people would use a percent method. However, the proportion would make your answer and thought process more clear. Some people would find it easier and more suitable to use a proportion over 100 and cross multiply for the correct price. I don't think this would be the case here, though. Setting up a proportion takes longer. Overall, the methods will give you the same result if you carry them out correctly, which is why there is no true correct answer to the question.
When I first got the blog prompt, I was kind of confused by it, because right now in Math we're studying geometry and circles. However, today Ms. Moon taught us that percentage can be used in finding the degrees of certain parts of circles. For example, to find out the measure degree of an area that encompasses 40% of a circle, you need to multiply 360 (since there are 360 degrees total in a circle) by .40 or .4. This, however, is a real-world problem that uses the same basic principles and knowledge. Percentages and ratios are two of the most useful and applicable things to learn in Math this year. I hope we can find other ways to use them and learn about them even in other classes.
