For 2.1 above, you are asked to cross-multiply to check if a proportion is true. Please do that for the exercise this time. However, I'd like you to think about the other ways we have of knowing when a proportion is true. For example, we know that a proportion such as 1/2 = 2/4 is true, even without cross-multiplying. Be ready to talk about the problems for 2.1 in which you really need to cross-multiply to check the proportion, and which ones you could test in other ways.
