Question: You know how to compare fractions using cross products, LCD, reasoning. When is it better to use one method over another?
When both denominators don't have numbers that are in common, you would use cross products or reasoning depending on if the question is hard to do in your head. But when the denominators can be equivalent, then you would use LCD to find out which one is bigger. But easy problems like 2/4 and 1/3, you can use reasoning because you already know how much 1/3 is and how much 2/4 is.
