by what number can we multiply 82778 to get 1? I figured out that I needed to use a fraction in the end. I am only mentioning this problem because the videos related to the exercise didn't explain how to solve this particular kind of problem. Maybe it is explained somewhere else. I love your site though, thank you so much.
