How do you use percentages?
In my job, we need to compare the demographics of our results to the demographics of the population. One way we can do that is with percentages. For instance, if we look at the population and see that it is 50% male and 50% female, but our sample for a radio study we are doing has a sample that is 25% male and 75% female, we know that we need to have more male participants in the study.
I would say the single most important way I use percentages in my daily life is the display on my smartphone that shows me the percentage of battery life that is left on my phone.
